Cheogram periodically forgets my contacts

First I wanted to give a shout out for the amazing work by the jmp.chat and cheogram teams for offering a great alternative to Google voice.

Now the issue; sometimes when I open cheogram it seems to forget my contacts. So all of my existing chats just show the phone numbers. The group chats still have their names.

Then the names come back later, but the problem is pretty common and renders SMS nearly impossible.

Anyone else have this problem?
