Text to work exactly like Illustrator, InDesign, Photoshop
Why didn't you start with the code for InDesign and strip out the print specific features and go from there? Forget that you've spent money, time and development trying to mimic workflows from Sketch or especially Figma.
Designers do not need everything to be automated.
Creating and editing text should be exactly like it is in your flagship programs. Click and go or drag a text box and go. No silly auto width, auto height or fixed. Just an open box where type flows as one changes the size or scales as one does with a modify key.
In the attempt to please newbies, (mimic Figma, Sketch, InVision etc) you've alienated us long time Adobe users (since 1992). UX data applied should be based on experience and efficiency from proven use case studies and user journeys, not what newbies looking to get work done quicker from templates talk about.
Whatever UX data you found was wrong or at the very least, misunderstood and misinterpreted.
Postscript type was a founding pillar of Adobe and that should be EXACTLY the same through all applications.
