The vacuum seems to work great, especially when compared to another brand that I was using before. I shared the vacuum with my spouse who is the one who uses it the most. Whenever there is a notification from the vacuum, I get it on my iPhone, but my spouse does not get any notifications. I have every setting imaginable for notifications, but she still does not get them. We both use iPhone 12 Pro Max, iOS 14.4. The vacuum is using firmware 1.6.97. Perhaps the problem is because we named the vacuum “Wyze Guy.”
