Duplicate username for different user IDs
Several years ago I created a Jami account with username and then I lost password or something else. I don't remember why I didn't use it.
Maybe a year ago I created another Jami account. I've used it on my Linux desktop and on android phone. When I copied this account to the phone app, I tried to add same username as in my first account and I got it. Same name was applied for this account on the desktop app.
Today I found a backup of my first account in
.local/share/jami directory and restored it on the desktop app. But username also was restored and now I've got two accounts with the same username.
Then I made a backup of my first account again and deleted it from my desktop app.
But now when I search my account in a desktop app I get two accounts in the search results.
I would like to understand what's happening and how to delete username from one of my accounts.
