Axolotl on UbTouch: Add contact and join group issue.
- 
 First, I am aware that this is not the best place to ask and I did check the issues on GitHub where a similar issue has been filed, but I need some sort of urgent quick fix for this problem and I am sure that some people on the forum will have faced the same problem and may know how to fix it. I received an invite to urgently join a signal group and Axolotl tells me that this feature is not yet supported. It says "In order to join please send private a message to the other side to exchange profile key..." So I sent the group admin an individual Signal message, he deleted me from the group and rejoined me via the new message with the same result. When I try to set up a group myself I just noticed that I am unable to add any new contact to the Axolotl contact list neither via UbTouch contact app nor manually nor by adding a contact via a received signal message. 
 I am using the latest Axolotl version (1.0.8 on FP2 running OTA 20).I updated to OTA 20 only a couple of days ago and noticed this behaviour only after the update. Could this have something to do with the OTA 20 update ? Again, I know this may not be the most appropriate place to ask, my apologies but any help is appreciated.

 @nogoogle : Best place to ask Axolotl-specific questions is the Axolotl Telegram group, you can find the group link on the app's website Axolotl.chat .

 Maybe you can work around this by using the desktop client to register to your group.
 I cannot test anything at the moment, so that's the best I can come up with...

 @applee Thanks Applee. That was the first thing I tried (I am using the native Signal desktop client for Ubuntu 20.04 most of the time) and accepting the invite gives an unspecific error mesage asking to contact support. 
 I have not tried to de- and reinstall Axolotl though.

 That is weird...
 Good luck with that
