Android client displays Jami ID instead of username for some contacts

Hello:

I have this weird issue - I’m using the latest beta of the Android client from the Play Store: in one account (only in this one - it’s originally an old Ring account) the client stops displaying the usernames for two users that I’m chatting with and displays their Jami ID in the conversation list window.

This behavior is very annoying.

It does it only for these two and only in this account - I have a Swarm chat with one of these users in another account and it displays the username there fine.

I have experimented with deleting this account in the mobile client and then adding it again in the mobile client from anonther device - my PC.

It adds it fine, displays the usernames fine for a while - couple of minutes or hours - then the display of these two chats gets mangled again, displaying only their Jami IDs.

Also, this account on my PC displays the two chats’ usernames fine - no such problem.

Can anyone help me with this? What could be causing this strange behavior?
