I have been having the same problem and came here looking for a solution. Very disappointed to find out that your support team knows of this issue, has marked it as "resolved", but has yet to take care of this issue.
I will not be recommending this product and will be giving my recent purchase a very bad review on Amazon if this isn't fixed swiftly.
The Rapid Ring app seems to have helped me. Installed about one week ago. The settings appear to override the Ring app. Still testing, but my motion hasn't turned off so far.
I just realized my motion alerts keep turning off as well. Tried all of the suggestions posted here but still not working.
Ring, please fix this issue!
