I updated Thunderbird to 102.0 without issue. A couple of updates later, I have102.5.0 installed and can't send email. I either see the Send button dimmed, which means send is disabled, or the Send button appears normal but clicking it produces no effect - no email is sent. Trying to send with several different GMail and Microsoft Exchange accounts all has the same result. I have tried * checking SMTP settings (all fine) * restarting Thunderbird * restarting my computer * reinstalling Thunderbird * reinstalling Thunderbird 102.0 * sending from the same account(s) using webmail (this worked) * sending from the same account using another email client (this worked) Clearly the issue is with Thunderbird, but I can't find any help item that covers this topic. Would much appreciate help or advice. My setup: * Thunderbird 102.5.0 * Macbook Pro M1 with Monterey 12.4
