Yeah, it’s goofy. Apparently the same thing exists with sound detections.
If you were using Android, then I’d suggest reporting your app version and doing the cache-clear-logout-login dance to see if that refreshes your settings, because your description makes it seem like your settings choices aren’t sticking, but I don’t know what to do with iOS since I don’t use that.
In any case, I understand the frustration. This product seems like it might’ve been released a little prematurely. Hopefully future app and firmware updates will continue to improve its performance.
