Hi. Not sure if anyone else is experiencing this. Page names seem to keep disappearing (the name of a page in the Pages panel is literally blank). I once noticed that an entire page was gone (along with all the layers), but now it just seems like a page name. The page remains, so I continue making changes to the layers, but I have to go and add a name to the page again. This is annoying and might lead to confusion with the stakeholders. Any fixes for this?
This sounds like a bug, so send the details about it (including file links, screenshots or even better video recordings) to Figma support team via the bug report form. But first make sure nobody is doing this manually accidentally, check the file version history and see maybe you or someone else made this change.
When renaming a page make sure to hit Return after typing. If you hit Esc it’ll actually clear out whatever you typed. And yeah I’d echo what @Gleb said about making sure no-one else on the team or in the file is accidentally renaming the page to be just a space (blank).
This issue seemed to occur after I created a new frame, and then changed that frame to a component. It might have also occurred after I created a variant of that component. I’m not sure. But I did find the diff in the version history. I’ll post screen shots. You see the difference versions in each image.
