Forum der Gemeinschaft Thunderbird for Android

Currently, I am using the desktop version of Thunderbird and I have my email account configured to digitally sign my emails with an S/MIME certificate. I cannot find a way to import my certificates on the android version of Thunderbird. Is there away to setup certificates in the Android version of the app?

In the Android version of Thunderbird if I receive a message from a group of bulletin board for example how do I reply only to the sender and not to the entire group?

I am running Thunderbird Beta on Huawei P30 light and I do not get notificarion for incoming rmails. As far as I can see all notification setting are enabled. Please help.
