02/09/22 Latest update really sucks! The screen flickers every time you move on the screen. Like you are taking a screenshot. Was a great app. Too many ads lately to upgrade, etc. I already pay. Also, place alerts are laggy now. Sometimes take 30+ minutes to tell me someone has arrived somewhere. 12/01/21 - Generic response from developer. This is happening for many people on different phones, etc. Not a settings issue. And no mention about advertising.
