Thunderbird stopped receiving emails from AOL. Stopped a few days ago and suddenly started working a few hours later. Now it has stopped for days. I can get my AOL emails by signing into AOL but I prefer receiving them in Thunderbird. I checked to see if my other devices have the same problem - they do. I cannot send messages from Thunderbird AOL account. Thunderbird does work with the Gmail account I have setup inThunderbird. What happened?

I checked with AOL. It appears that Thunderbird can send emails from my AOL (Verizon) account but it can receive them. This is either a Thunderbird issue or an issue with our Internet Service provider (Verizon).
