Every time my login is on two devices my notifications stop on one and I have to log out of both devices, put one in airplane mode and log back in on one so I at least get notifications on one. I have tried this on two devices at a time on 4 different devices in every combinationall running the most updated IOS and Wyze software over cellular and wifi also in every combination of the two.
