My brother uses accessibility apps on his IPhone 13 Pro. He uses high contrast and inverted screen, text to speech and zoom controls, and since the 16.3.1 update, the accessibility features will stop working and he has to shutdown.When he tries to reboot his device, he gets a pinwheel and he has to do a forced shutdown (multiple attempts) in order for it to work again. After multiple visits to the Apple Store, they reproduced his settings on a phone not connected to iCloud and it reproduced the same errors. They concluded this update has affected the accessibility features. The same thing is happening on his iPad. Has anyone else experienced this issues? Know of any fixes?
