I suspect this started occurring with the latest Ring app update. My Stick-Up Cam Wired is also just 2 weeks old and it was great until the app update a couple days ago. Sadly, that app update DID fix 2 issues I’ve had with Smart Lighting so it’s been a mixed blessing.
Hopefully, Ring will get it all sorted out quickly and release another app update which fixes this “Low Battery” issue (especially since the camera has NO BATTERY because it’s wired).
