OK. I read that cover to cover. I will test again. I do think one of the problems may have been caused by me first installing the Flatpak from Fedora Repo, then changing to Flathub repo. I am now wondering if the simplest thing to do (if I can suss how to do it) is to just: 1. SAFELY back up all TB data. 2. Uninstall TB 3. Install RPM version of TB 4. Import my data If nothing else this will at least put my profile where TB expects it to be. (if I go to troubleshooting information, in Application Basics section it says "Profile Directory: (Local drive)" with an 'Open Directory' button that DOES NOT WORK, if I click on it nothing happens.) I suspect running RPM version may make things easier and perhaps function better. Do you have any comments on that idea? And if it sounds wise to do, how can I safely back up my TB data before uninstalling the Flatpak? thanks
