So. Better to set up like new AW. I don't know if its working with old backup. But if it does, its mean that problem was with certificate. So you must reactivate it after synchronise finished. Also, i know that you can change language (on iPhone) after. You can try change region and tell us if all is ok. I don't want to risk right now because i spend two days to solve this **** and don't want to synchronise it again)).
Yeah no problem about the changes of region and language ! I'm back on my region on my iPhone and on my AW !
2 days !
The solution is by you ?
