Since updating to beta 2 this morning I've been unable to use iMessage pretty much at all.
The Messages app itself shows just an empty page with no conversations, and the 'new conversation' button doesn't work at all.
The Messages settings itself shows me as signed out.
If I try to sign in, it spins for a long time and then just shows an error of :
"
iMessage Activation
Unable to contact the iMessage server.
Try again.
"
I'm guessing the only way to fix this would likely be to restore an old backup from quite a while ago or wait until something changes?
Restoring would lose me a ton of health kit data and apple watch data which I would be super sad about.
