Thunderbird for Android Community Forum

Hi everyone, I’ve been using Thunderbird on Android for emails, and I’ve noticed that notifications sometimes get delayed when I’m gaming on my phone. During longer gaming sessions, emails don’t show up right away and only appear after I exit the game or switch apps.

I’m guessing it might be related to background app restrictions or battery optimization, but I’m not completely sure. Has anyone else experienced delayed notifications with Thunderbird Android while gaming? Any tips on keeping notifications timely without affecting game performance would be really helpful.

Hello on my Samsung S24 synchronisation of email became very slow for a few days. I trier to réinstall TB but it did'nt change anything. Do you please have any idea where could be the bug and the way to fix it ?

The Thunderbird for Android app updated yesterday to version 17.0. Ever since the update, I've noticed an undesired behavior (bug?). Whether I have one new email or have several new/unread emails, whenever I read the top/latest email and then delete it, when returned to the Inbox list of emails, the message I just read and deleted will show that it is still there and unread. However, if I simply touch the screen and drag the list of messages upward or downward slightly, then the email is deleted (removed from the Inbox).

The same behavior happens when simply reading the first (top of the list) message and return to the Inbox... the message will show unread, but if I drag the list up slightly, it will then show the email as having been read.

This behavior does not exist for other emails in the list, only the first one (top of the list/latest to come in).

Perhaps I'm not the first to report this new and undesired behavior. Is there some setting that I'm not aware of that I can set to correct it, or does it need to be fixed in a future update? I tried rebooting the phone last night, which made no difference to this behavior.

I'm running a Samsung Galaxy S22 running Android 16.

Tbird (v16. 1) for android installed on my Pixel 9a connected to my gmail account. Gmail client runs perfectly connected to same account while Tbird starts with a blank screen i.e no messages. App appears to be frozen but later displays messages. General operation seems sluggish - enough to turn me back to the Gmail client (which I don't like) but at least I can navigate my email without waiting. Any suggestions please?

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.

When I first open K9Mail 16.0 or after scrolling to the top of the message list, the message does not disappear from the list after I open a message, select move, and choose a folder. The message will no longer be clickable after I do this. However, it will remain displaying in the list until I start scrolling the message list, at which point the list updates and removes the moved message.

Please fix this bug.

Thanks.

Just installed TB for Android on Samsung S24 Fe. Works fine but am unable to exit the application other than forcing phone back to home screen. Have installed on a Samsung tablet and the back button seems to be working OK. Anyone know of any issues with this phone and TB?
