App always worked fine, but after the last update it is slow as .... and although the app does not really crash, it becomes unusable from time to time.

Thanks for the feedback. We're sorry you're having issues with slowness. If it's in the message list, try: Settings > General Settings > Display, turn off “show contact names” and the “show contact pictures” settings, as in some cases this can improve the issue.

Dear Sir/Madam, I apologize for having to inform you that your solution—after various attempts such as a reinstallation—did not resolve the problem, as I do not automatically receive my email after 15 minutes, meaning I do not know if I have any mail.

Ugh, sorry you're still having issues receiving your notifications! Can you please also try going into your phone's Settings, then into Apps and then Thunderbird, and in the 'Battery' permissions make sure Thunderbird has unrestricted permissions? Thanks!

Hoewel het fijn is dat Thunderbird al je mail-accounts kan laten zien, is het echt een gemiste kans dat je contacten niet met Thunderbird Desktop worden gesynchroniseerd. Zo ben ik op mijn telefoon geregeld contacten kwijt, wat de functionaliteit beperkt. Dat is ronduit irritant.

Op dit moment beschikt de app nog niet over een adresboekcomponent. Voorlopig kun je toegang tot de contacten op je telefoon inschakelen via Instellingen > Apps > Thunderbird > Machtigingen. Bedankt!
