iPhone XS 256GB, Recently upgraded to iOS 15.4, now 15.4.1. Now iMessage and FT doesn't function as it did before iOS 15.4 upgrade. iMessage has been cycled and it is registered. AppleID signed off and on. Accounts & phone# verified (hasn’t changed). When I go to msg someone/anyone that had been via iMessage now appears as SMS. All FT fails. I have tested this both on cell and WiFi. Any help appreciated.
