Ring Unofficial App -Snapshot Prerequisite Error No installed devices support snapshots. Please install a device that supports snapshots before continuing

I have installed the unofficial Ring App and created tiles that don't show the thumbnail. When I go back into the app on display thumbnails. I get this error:

Snapshot Prerequisite Error

No installed devices support snapshots. Please install a device that supports snapshots before continuing

In the top left of the tile, I get a broken image icon.

Any Help would be appreciated,
Scott
