Pulsing white light followed by solid white light on Video Doorbell Pro?

Ring sent me a replacement Doorbell Pro to replace a unit that died (it required re-connecting to the network every few weeks, then stopped connecting altogether). The new Pro installed without issues, but about 30 minutes later I noticed it was disconnected. The unit was unresponsive. I've tried resetting (30s side button press) and power cycling it (leaving it off for 10 minutes) when it starts up the button spins white once, then pulses white for a while, and then ends up with a solid white circle. Anyone have any idea what this means? I'm using the 16V/30VA supply that Ring recommends so I'm pretty sure it's not the power supply. I've tried calling customer support but after an hour on hold (and being apologized to by a pre-recorded voice more times that was healthy) I hung up. I have another Pro unit that is working fine, so maybe it's just bad luck with the faulty one and the replacement. While I'd appreciated any help for this specific issue, looking at the bigger picture, Ring's customer support is pretty bad, and their products are failing more and more often for me. Not a good combination for a home security system. I'm thinking of cutting my losses and ditching Ring (I own an extensive Ring security system + multiple cameras) and switching to a more reliable system with better customer support. Any suggestions?Thanks in advance.
