Sorry if this is a noob question but I am at breaking point.
A couple of months ago I tried to change my encryption password. Inadvertently, I created many passwords without knowing. Now I have a Joplin account with 7 or 8 different sync passwords, some I am not sure I will remember (still trying).
I can get into Dropbox okay and have a few of the sync passwords but not all. Is there a way I can delete old encryption keys so I can get my notes back?
Thank you for your help.
