I am trying to add a new email to Thunderbird. When I select Add Account I get the Account Hub modal to enter Name and email address. I then press continue and all I get is a spinning blue disk. There are no options to enter the details manually. I'm using version 140.1 I've looked at Automatic Account Configuration but that only seems relevant up to v128 and Manual Account Configuration hasn't been updated in 7 years. (The email account is working because I've sent emails from another computer).
