I’m not sure if it’s an iOS 15 update issue, I have 4 window/door sensors and the hub. Our internet went down, and when it came back on, YoLink is no longer functioning. There app says “ Connection failed, Retry please!
Error” lConnection Failed, Failed, check your
network please.” With a reload button. Reloaded. Disconnected hub, nothing! I still get app notification for ONE sensor, but when I touch that notification to get into YoLink , “connection failed”. I have it 1 stars because it did work, and still works with one window. I just need it to work how it did. I will put it at 4-5 when it starts working.
