When the grid is center, the right margin is false, 6 pixels too short.1 vote
We’ve filed the bug and will be fixing it in an upcoming release.
When you create a symbol with some shape and text and the text is subtracted from the shape, then modifying the text in one instance changes the text in all instances.
It seems in such a case text is treated as shape instead of as text and therefore changes the symbol itself and all instances.
I've attached a sample .xd file that illustrates this issue.1 vote
