I had not, but after reading your post I did and retested. Running through the procedure, as far as I could tell, nothing got changed and at the end it said “No more issues found! You should now be receiving notification from your device.”.
Upon retesting, I’m still not getting notifications.
Before posting my initial question, I came across a similar thread (V2 and v3 cameras with camplus notifications don't notify). I’m thinking if this was a problem with the firmware update a lot of people would be having this issue and there would be a lot of discussion about it. Not finding that, made me wonder if it was newbie error on my part.
