Pro2 wireless camera shows sync'd but offline. Tried rebooting Base Station, swapping batteries, etc

One of my 4 Arlo Pro 2 VMC4030P cameras just went offline today.  I replaced the battery, the camera recorded me approaching to do this.  I press the sync button, the blue light flashes which should mean it is sync'd.  The camera still shows offline. I have rebooted the base station, swapped batteries with other cameras.  No changes.  All other cameras are still working.  Has anyone encountered and/or fixed this issue?

App or browser? Have you tried both? Have you force stopped the app and reopened it?
