Apple Home app wonky on my iPhone but works fine on my Mac and my wife's iPhone

I had a brief power outage at my home. Shortly after power was restored I noticed I could not do live view of any of my 5 Home app connected cameras, including my Circle View doorbell camera. If I click on the camera icon I get a spinning cursor for about a minute and then a message, "No Response". This camera is not responding". But if I access any of the cameras, including the doorbell, through the Home app on my Mac or on my wife's iPhone, everything works as it should. This clearly shows that the problem is an issue with my personal iPhone and not an issue with my network, router, camera devices, etc.

I have shutdown and rebooted my iPhone multiple times with no resolution of the problem. My computer and my iPhone are both signed into the same Apple ID.

Any ideas what might be happening and how to correct it?

Thanks.
