Saw this post related to smart alert on ring doorbell pro 2, similar to my issue. Detection stopped working after functioning properly for more than a year. Called support after several unsuccessful attempts to increase detection. Apparently a script for fixing this issue has already been written. The fix is to remove Smart Alerts. When I questions why it worked for more than a year and stopped working suddenly ie a bad firmware update, they could explain (not in fixit script). Told me this Smart Alert feature takes up more processing time and a warning detection might be delayed by using this feature was always a possibility. 5 days not working is quite a delay. Pretty sure software update not working properly. Works fine with Smart Alerts off....not so smart if you ask me.
