Better than most xmpp apps – Monal - XMPP chat Review

I’ve tried several xmpp apps, and so far Monal has given me the least issues. However, something that really bugs me is that you have to individually delete every single message, because there is no option to clear all messages or even delete a chat. Also, every time I delete a message it sends a spam message to the other user, such as “there was an error decrypting this encrypted message”. Quite annoying.
