Apologize for posting this (again). Apparently, this is a known issue, but the last post was back in Dec'20, so maybe there is a better solution.
I have the latest version of Joplin on Windows, Android phone, iPad, and use encryption that has worked just fine for the last two years. After the last update (Joplin 2.4.4 (prod, win32)), I received that orange banner saying "One or more master keys need a password". If I click on it, I see that my (single) master key is valid, but then there is one "missing" and no prompt to perform any action, like re-validating my master key or anything else.
How is it possible that there is a warning or error, but there is no prompt to fix it? Searching the forum did not help either and I see that people who experience this exact error found no solution. Is there a way to fix this?
By the way, my other PC with exactly the same configuration and version does not show this error.
