Wish I had found this thread earlier as I’ve spent a frustrating week trying everything to troubleshoot my brand new Stick Up plug in.
Live view almost never worked, only occasionally after power reset. Recording was 50% reliable at best.
Have a Spotlight camera which has worked perfectly for over a year so obviously not a WiFi issue etc and I know the Ring products and way of working.
Anyway, managed to return the stick up and got another Spotlight, and it just works like you expect it to. Not that Ring earned the upgrade but obviously worth the extra cash for me.
It seems to me like a clear model or, best case, firmware issue.
