I have IOS 12.5.5 on an old I-phone 6 plus. The Wyze app quit working this morning 12/28/21 and I’ve wasted an hour or two thinking it was my phone. I should have know it was a Wyze problem. Wyze support is very bad and I’ve been waiting over a week now for a response on two outdoor cams and a base station that quit working last week. I have 27 Wyze cameras and wish I would have bought another brand.
