Solved Join: Stuck on "Trying to find your phone number..."

In case of fresh installation I can't get pass The Enable SMS and Phone Calls,

And if I skip that,
The SMS and Calls are not syncing;
on the settings : the "Enable SMS and Phone Calls" toggle shows active;
and if I try to Enable after Disabling, the same thing happens, it gets stuck!

any remedy?

 

Well, i discovered the solution myself,
that is patience!

it seems that the screen wasn't stuck, actually it takes loooots of time!
