It did repeat itself, yes, before I started rebooting regularly. I'll do an experiment starting tomorrow morning. I'll reboot and note the time. Then just leave it and log the time I notice the notifications failing to make a haptic signal. Then repeat so I can make a consistent observation on how long it takes for the bug to recur. Right now I'm vaguely stating it takes about 2 days. Let me get a more precise reading on the interval.
Great if you can report back that would be great, I'm also reporting this to Apple and the more data the better
