axolotl [BUG] Can't be added to groups

Description

If invited to a group Axolotl tells me to exchange a private message with the group's admin and "... After that he/she has to remove and add you again".

But on Android there is no way for the group's admin to "remove" or "add" a user. All he/she can do is revoke the invitation and invite me again.

If he/she does so - after exchange of private messages - the group's name will appear in my chat list but all I receive is the message "Group was changed to revision [#] Group changed". I'm still unable to post or receive messages in that group.

The above message "... After that he/she has to remove and add you again" remains.

Steps to Reproduce

see above

Versions

Axolotl Beta 1.0.5

Device

Fairphone 3 OTA 19 stable
