I have tested ring on my android with lineageos 14.1.
When I try to send a message, it doesn't work: it says the message is
being sent... But I never receive them on my other device. I can receive
messages though when I send a message from my other device to my android
device... If I quit Ring, I can't open it anymore, I have the welcome
page with a circle that keeps spinning.
I try to delete it, retry everything. I have the same problems. I try
with the fdroid and the google play version. It's the same.
Is it a know problem?
