I don't know if it's related to the recent firmware updates or the latest iOS app, but I'm getting ridiculously wrong counts of unviewed events from the app. Once I noted the behavior, I restarted my HB and formatted the SD card, but to no effect.
Since I formatted, for example, I had a notification pop up. I dismissed it and unlocked my phone to see I had 6 events to view. When I opened the app, there were only two. Later, I got another notification. This time, though, the unviewed count showed 10 on the app, while opening the app showed just the one new video for a total of 3 recordings.
None of my other settings have changed.
