Issues with iMessages after iOS updates

Hey there,

After updating to iOS 15.4.1, both our 11 Pro iPhones, and our 4 iPads, cannot iMessage either to see received messages or to send new ones. The app opens only to a blank white screen.

all these devices worked perfectly prior to the iOS update.

we have gone through every “fix” in the book, including while on-line with Apple support. Even did a reset of network settings, and a restore of the 15.4.1 update while connected to our iMac.

Our phone service carrier AT&T refreshed signals to both phones several times, they found no problems with our cellular service.

Our internet works fine as well, and the problem persists whether we are home or away from home.

also occasionally we get the same blank white screen when try to use the phone to answer or make a phone call.

None of these issues existed prior to the iOS 15.4.1 update.

Highly unlikely that 6 separate devices (2 phones & 4 iPads) which worked just fine prior to the same iOS update would suddenly fail right after — this must be something caused by the iOS 15.4.1 update.

Very frustrating

We have already tried all those fixes & several others already, nothing helps.

the iOS 15.4.1 update completely crashed iMessage function on 2 11pro iphones and 4 different iPads, all of which worked perfectly prior to the update.

took all devices to Apple “genius bar” this morning, spent 2 hours there & they could find no problem with our devices.

Apple needs to release a patch for this issue — we are not the only customers with same or similar problems since recent iOS 15.4.1 update. (Brand new devices are fine with update; those phones and iPads a couple of years older are having problems.)
