Thunderbird for Android Community Forum

I went out of the USA on May to Ecuador and Peru, and on the same day the Android version of Thunderbird stopped retrieving new email from the server. I have used Thunderbird pointed to the same server on Windows 11 and Android successfully for years. I thought it might be something to do with being out of the country, but now I'm back in the USA, and sync account on Android still does not retrieve new mail that has accumulated since May 4th. I've been following my email using a webmail access so I know there's lots of new mail. I've closed and reopened Thunderbird on the Android, and I've tried sync account with the webmail access closed. I have not yet tried Thunderbird on my windows 11 laptop because I'm still not home yet. Any suggestions welcomed, thank you for your help!

Unified inbox. Have to delete messages twice (first time only marks them read).

When I delete a message from the Unified Inbox by swiping right (and confirming) it only gets marked as read and not deleted. Have to swipe right once more (and confirm) to make it disappear.

In the normal inbox it is deleted at the first swipe to the right.

Why does it only get marked as read at the first delete in the Unified inbox?

A bit annoying having to delete evey message twice in the Unified inbox.

I tried to connect to my personal outlook email account on a fresh installation of thunderbird mobile. The setup wizard gave the correct configuration as described in microsoft's official documentation. But the following error occured: Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox.

IMAP is enabled in microsoft's mail account settings on outlook.com.

I have app version 18.0. About 20 minutes ago I composed an email to a new contact (responding to a letter he sent me). The email was ready to be sent but before I did so I passed the phone across to my wife to read it. She passed the phone back and the message had disappeared from the screen. I have two email accounts that are Unified. The missing email was written with the main account so I checked in all those folders, including Sent, Junk, Spam, etc. I tried searching for the recipient's email address and tried Search everywhere. I also checked on TB for desktop on my laptop. I thought that composed messages were automatically saved. I have seen this during composition when opening a different app to check something and a message appears at the bottom of the screen "Message saved as draft" or similar. I'm trying think what is different this time. Can you offer any suggestion?
