Are any other @thunderbird users seeing the issues that @winterschon wrote about in this post? I've been seeing the high resource usage, just not quite as high (but almost as high). This is one of the reasons that I'm moving back to Emacs for my email or looking for a client that is a bit "lighter" on the resource usage.

We've been talking a lot about roadmaps for the last four State of the Thunders, and this volume is all about priorities. How do we set them and decide on timing for certain items? How do we make mid-development adjustments? And how do we make sure our priorities are in line with what our users need?
We're also updating you on Thunderbird Sync (Yes, Sync!), Thundermail and the Pro suite, as well as our mobile development. Watch on TILvids:

Heading to #KotlinConf later this week? So are two members of our mobile team! Be sure to say hi if you see them in talks and in the hallway track, and we've even been told @kewisch is bringing some Thunderbird for Android stickers to share!
that sounds terrible!! Why spend so much resource (time, human and money) on something so closed as Apple's ecosystem?
I think you should put effort on improving interface and other features, to a point where #Thunderbird could be a strong plus for Android.
Don't get me wrong, Thunderbird mobile is good, but it can be so improved yet!
We've had a few iOS updates in the last few Android Progress Reports, but with more substantial iOS news, it's time for a name change! So here's the shiny, new(ish) Mobile Progress Report! ✨
Last month, we published our initial iOS repository, made plans for Testflight and laid out our intended initial features. We also discuss initial release engineering and localization decisions. For the Android app, we made a LOT of fixes. 🔧

@OctaviaConAmore It's not too clear whether donations to the new MZLA entity are earmarked exclusively for #Thunderbird development, or can be harvested by the parent organization to fund other projects.
I'd want to know because recently I've been donating to Thunderbird and I wouldn't like my donations to be redirected to #Firefox, given its current leadership and direction.
@thunderbird is this known issue with the rebranded #K9?
I composed a message while out and about, but the message didn't send because my mobile provider has ended up on #Spamhaus #XBL. The message sits in the #Thunderbird Outbox.
On getting home to my WiFi network (whose internet connectivity is provided by an entity which is not my mobile provider) and attempting to resend the message in the Outbox, the message still fails to send, with the same error. However any email composed and sent while on my home network is sent reliably.
What's going on there?
