Mozilla Thunderbird for Android is now available in beta, built upon the K-9 Mail app.
The beta includes core email features like account setup, email organization, and notifications, with feedback encouraged from users.
Thunderbird for Android will remain a separate app from K-9 Mail, requiring users to migrate if they previously used K-9.
Nice to see progress, but so far it seems indistinguishable from K-9.
The feature to import settings from K-9 doesn’t work for me, possibly as a consequence of running CalyxOS.
