All I got this on one of my cameras. The others were fine.
What I did was went into
- Settings within the camera view
- Notifications Video and Photos (at the very bottom)
For some reason this was off on the impacted camera but still on for the others that were working fine.
I toggled the switch to on and closed the app went back in and the message shown was not displayed and the alerts worked fine again.
The camera in question was a dome 1080p. The others are Home 3.
Maybe worth a try.
Let me add this appears to have happened after I upgraded to the latest YI Home app version. Notifications / alerts prior to the app do not work and new ones were not until I followed what I’ve mentioned above.
