So this is two issues. For one I know have the issue for over 2h that my messages won’t send. Neither on my phone nor on my desktop. Restarting the program or device didn’t fix it. The weird thing is that I can still get messages, however the other person doesn’t get my answer
The other issue is said messages I get on the desktop app only show me the block of text over and over again that the message couldn’t be decrypted even though it did that just fine before. The FAQ was useless for the issue and I couldn’t find a similar topic on the forum.
I am using a @web.de mail adress and as a extra bonus thing the section how to set up that adress is lacking the information that the POP-3 and IMAP support needs to be activated.
