After the AWS issue, I found that I was not being notified of AI either. This was an issue I had in the past. To correct that, I went into each device, turned off Event Detection and then Notifications. For me, it was important to go into Cam Plus AI in Event Detection and turn off each AI I had selected, then Back out of that menu to ensure it commits the changes. I would then go back into Cam Plus AI and select which AI option I wanted and Back out again. Then I would go into Notifications, Turn off AI Notifications first and then Notifications as a whole, then back out one menu again. Then go back into Notifications and turn on Notifications and Select the AI options.
Once I did this, I started getting my AI notifications again.
