I leave my ipad switched off overnight. A colleague usually sends an imessage to me at 6 a.m. which i used to receive when i switched the ipad on at 9 am. This no longer happens since i updated to ipados18. iMessages still arrive as usual on watch and iphone which have all been updated. Anyone having the same issue? My partner has also updated to 18 on her ipad and the same problem happens too. Really annoying!
