Push notifications stopped working again

I recently posted that I was not getting push notifications from my cams. After the last update I started getting notifications from 2 of the 3 cameras I have installed.

I researched my problem and was advised to reset the cam I wasn’t getting notifications from. After I reset it I started getting notifications within 5 minutes. The cam worked flawlessly for about a week and all the sudden I am not getting notifications from the same camera again. 2 of my cams work fine, and 1 doesn’t. Should I have to reset the 1 cam weekly?
