Ring Alarm Pro keeps failing to Cellular

WE bought a Ring Alarm Pro right when they came out and moved our network to it so that we could take advantage of the failover internet. Sounded Great.Except. It randomly fails over to the cellular and stay there, I've never been able to get it to move back to the primary internet without removing it from the eero network by replacing it with a different eero gateway and then swapping back again. It's happened 5 times now and i'm probably done using it as the gateway router for the house. Anyone else with the same problem?
