What issue do you have?

I have been playing quite a lot with 2 accounts in Joplin Clouds. One with my home notes that have been working for a year or so (on multiple Mac and andoid and iOS) and one new for my office notes. The goal was to have on the second account with my office notes (imported from Evernote) encrypted and the shared notes (not encrypted) of the first account. Some devices would remain on the first account with the home notes and some device with the office account and shared notes of the first account.
For this I created a second new profile in which:

  • I imported all my office notes and let it encrypt on my Mac
  • then let it sync on a new profile on my Android

I had some issues with encrypted notes that would not decrypt but this is another story. After a long while I had my office devices with my office notes almost perfect except a rather few notes that would not decrypt. I then shared from my first profile (home notes) 2 large notebooks from another Mac to my new account. I then synced the second profile to get the shared notes. At this point I started to have quite a lot of conflicting attachments on the shared notes that I could eventually remove and then after quite a lot of time all would be well on both profiles both Macs and one Android (2nd profile only).
Long story short I finally had to get rid of my office notes, my office profile and come back to the original setup only with my home notes, one account and one profile for all devices as originally. I removed the share. Again quite a lot of conflicts that would eventually solve themselves with a bit of help.
The problem is my Android device with profile 1 (home notes) that I had not synced for a few weeks on this profile anymore also generated a lot of conflicts attachements and then started to fill my memory. I had to stop this since I could not recover space. I finally deleted from Android the first profile, tried again and did not release memory (65 GB while the notes should take about 15GB). I then uninstalled Joplin, reinstalled, recreated a new profile, synced with the account 1. The sync does nothing and turns for a looooong while. Finally I get a message Error Gateway Timeout.
I am not able to get my notes back to my Android anymore. One new note that was on the Android synced to the other devices with profile 1 fine but notes of the other devices are not coming back to the android.

Not sure what is the best way to get back on my feet. Is there a way of reseting everything and start again?

Any suggestion?

Thanks
