I’m not sure if this is some niche bug or we’re supposed to do something when working with an older file, but I was updating a pretty old file about 1-y-o and when turning a frame with nested items into a new component I couldn’t find the option to add a text property to my component when a text layer was selected. I looked it up and didn’t find anything similar.
I ended copying over all the elements outside of it and creating a new component that’s configured the same and the text property option appeared. It could just be a coincidence that the first one was an old layer but it’s the only difference I noticed.
(P.S. UI3 is annoying, tried for a couple months and it never became as intuitive as the original UI over a week of use...)
