Hi,
I use Joplin on phone (Android 13), tablet (Android 7) and PC. Since last update few days ago, app on tablet has major issues. I can run it. But when i click on "Synchronise" or "Configuration" it closes and i get message "Joplin keeps stopping". I tried to reinstall it from Google Play, same. I tried to install older versions from F-Droid, same thing. But 4 days ago it was all good.
Joplin for Android v3.0.8 was just released and fixes a performance issue related to many nested notebooks. If there are a large number of nested notebooks, then this issue might be fixed in v3.0.8.
Alternatively, in the past, the slider component used on some settings pages has caused crashes on some devices (issue, upstream issue). We applied a workaround, but it's possible the workaround needs to be re-applied or adjusted.
I have this exact problem. I just installed Joplin from the Play store on my Planet Gemini device. I went to configuration to setup sync, but I get the 'app has closed' message every time. Does anyone know of a solution?
