WMU no longer works with iPhone XR – Wireless Mobile Utility Review

I if I could I would give this app a ZERO, This app no longer works on iPhone XR with iOS 14.6. It used to work in the field. On iPad 11 pro with iOS iPad 14.6 it works All settings on D7200 camera are identical. Settings on iPhone XR seem to be ok per YouTube instructions. Also, WMU on iPhone previously worked. Now screen is frozen on WMU except the WiFi symbol on top left shows when connected to camera. The settings on upper right of WMU is frozen. I have asked for Nikon Support re this issue three separate times. No response. Am I going to have to junk the iPhone XR and D7200. I do not want to carry iPad into the field! I want to use the iPhone WMU with my D7200. I have been on help line with Apple Care. They said there is no problem with my phone. Ultimately, the WMU app does not work on iPhone XR.
