What issue do you have?

No issues at this moment, just a question about Joplin encryption.

Why was my encryption key updated recently?

I have not clicked on re-encryption button. I have not had any messages about outdated algorithms. I have not created new keys.

Is there some key rotation mechanism that updates keys without asking the user?
In general, what are the cases when the "Updated" date-time value is not equal to "Created"?

Should I worry because the key was updated (and I don't know how and why)?
