Being able to share/edit is ESSENTIAL. Not allowing it is basically Adobe asking for users of this AMAZING XD Software to basically switch back to Sketch.
AND PLEASE - ADD RULERS!

We also work in a team of designers. We develop extensive applications. It is natural that several people develop different tasks for one application. In larger enterprises, there is even no owner of a given file / prototype. Teams are responsible for agile development of solutions for large applications.
At present, it is almost impossible to work in a team. Please, make it possible.

Thinking more about the security concern. If it is really that necessary to babysit updates (which sounds like an internal problem to me, not software, but hey..) Why not just list an update log in the same prototype export panel in xd on a second tab that shows the date / time / adobe ID of each link modification?

I can't imagine why this would be intentional. If you someone has the file, then they can make updates. Why would you not want them to publish those updates? If i don't want someone to make updates, i'm not going to give them access to the file!

I can't imagine that this type of file security is that big of a concern for users. I don't want to have to 'manage' accounts on my links or play the collaboration game. just make the links file specific. that's all we want.

To retain comments while allowing different contributors to update the prototype, each different contributor has to log in to the same Adobe login. Please allow a prototype to have multiple owners, so the published prototype can be updated by multiple contributors.

That's a key feature for us. Without we won't be able to use XD as our primary prototyping tool for our design system.

YES!!! We are also in the same situation, and definitely would like the ability to have multiple owners on the same file and URL.
We are a team of designers working with Jira, and confluence for documentation and each time we update the design we need to change the link.
what happens if the person leaves the company?
Please add this feature.

As a designer who interfaces with a developer team, I share my prototype link with them and then we collaborate through the development process. This works great except for when I access the file from a different machine than the one I originally shared the link from or if another designer does work on the same XD file. When we try to share a link from the same file but on another machine, we're forced to share a new link.

This is extremely annoying because it almost defeats the purpose of being able to update the share link. It requires us to go through all of the tech teams tasks and make sure that the new link is in there instead of the older link.

It would be nice if when I share a link, the link would stay the same even if the link gets updated in the same file but on another machine.

Also a Marvel App type of view of all projects for the whole team would be nice. Now the only thing as a designer I can give to my project manager(s) is a link. They can't log in to anywhere to see all the projects our office has with XD prototypes.

Yes! A thousand times yes! This is what we absolutely need. Multiple designers at our office are working with the same projects. How can you update the prototype when the creator of it isn't around? Even when you create a new link the prototype comments are gone, that's no good.

In (Publish) Design Specs beta, It would be helpful if Content writer is able to override the Content

Here is a scenario (in attachment) where the content can be copied, but its not final yet. It is bound to change. From designer perspective, I have done the best to provide enough place for the content. But on providing the content writer a permission to edit and override (atleast in the specs link), I can get this perfect based on the need.

Request you to consider an option of editing this based on permission granted to content writers

I work on a team of designers. We're working on establishing a company-wide style guide. We'd like to be able to have a shared Xd file that we all contribute to separately. Currently we can't all publish to the same link. So one person will have to take ownership of the prototype. It would be beneficial for us to be able to publish our changes into that master file.

Yes, same here. Was looing for it on the forums and the internet. This is exactly what we need. Specify a second (or even third) owner of the file, so we can both update the same link. This offcourse be an Adobe CC user.

Yes I second this! I'm collaborating with a colleague on prototyping our new website and it would be helpful to have multiple owners and levels of sharing access (similar to Google Drive where you can edit, suggest and view).

Hi Jacob,

thanks for the explanation. Yes, your explanation of the intended behaviour is correct. I would love to see that feature (multiple owners of prototypes) in a future version.
