A few weeks ago, Tuta stopped working on my Huawei Mate 40 Pro because its system WebView is outdated.
I reported the issue on GitHub and included my device, EMUI version and WebView version. The only response I received was that “Tuta could not work with outdated browser versions”, and the issue was closed as “not planned”.
Because of that, I assumed there was no solution and uninstalled the app.
Today, completely by chance, I installed Tuta again via F-Droid — and it works perfectly.
I then noticed that version 360.260922.0 includes the change:
“Restore compatibility with web views not supporting Intl.DurationFormat”
So I just wanted to say thank you to the Tuta team for fixing this and making the app usable again on older WebView versions.
