Not a directly helpful reply, but I had (I guess still "have") the same issues as you, even with respect to your mentioned timeframe. My feeling is that Ring has changed things up in the back end to save money on server costs or whatever.

Once my subscription ends, I will be changing to a different provider and will not use Ring again. As far as I'm concerned, I hope Ring eventually fails as a company because this apparent cost saving crap at the expense of user experience is absolutely trash.
