@adnan IMO, no. I know how big of a challenge it is to get a group to switch communications apps & in your situation I wouldn't.
I still trust #Signal & use it for my groups. If someone were just getting into using encrypted chat, then I would recommend #DeltaChat. I haven't experienced any buggy glitches, it has more upside & I love the community being built around it. It wasn't any harder for me to start using than matrix or mastodon.
