After upgraded from 1.0.178 to 1.0.179, the ‘synchronize’ button cannot be clicked (is disabled), making changes cannot be sync’ed to my OneDrive. As for testing purpose, I switched to dropbox and OneDrive (test), upon saving such config changes the sync button is enabled and I can do sync.
I copy an explanation by @tessus from another thread:
" First, please backup your notes: Export -> JEX .
Then close Joplin and delete the profile directory. The profile dir can be found in Preferences (the General tab) - Notes and settings are stored in: xxxx"
If you are on Windows you find the Joplin directory in %userprofile%\.config. After that start Joplin and authenticate with your OneDrive. You should not switch synchronization targets when something is not working, this makes things worse.
