I listed this in my bug list but didn’t have a post for it, but creating one now because it is still happening even after the recent update that I believe was supposed to correct it. We can use this thread to discuss it further if necessary.
The issue is that all the tabs disappear except one outline tab. Killing the app and restarting has fixed it at times in the past, but when it just happened again, upon restart the correct tabs appeared for a half second but then reverted back to a single outline tab.
