HomeKit Fail on one device only

We have three LogiTech CircleView cameras. They are all on the same electrical circuit and Mesh Node.

They all work the same on all three of our iPhones when assessing through HomeKit. But since updating to 18.6.2, one of the cameras does not respond on an iPad 8. I have done a hard reset, removed and reinstalled the app, both multiple times.

On the My Home page, in the thumbnails, two cameras show current or a few seconds ago while the non- responding camera shows image from 2 days ago.

These are the only devices linked to HomeKit and would like to add a few more, but the numerous problems with these cameras make us some what apprehensive about investing anymore time or money in this venture.
