Lost Email Accounts
Thunderbird on Ubuntu upgraded (automatically) to 115.2.3 (64-bit). 3 of 4 email accounts disappeared (not shown in INBOX, SENT, etc). However, going to Account Settings I see all four setups. All are POP. The only one that I see in INBOX was the first one setup. These have been working for years.
I do not understand proflles so need a lot of help.
