I click on my device to turn it on and it took me to the app settings. I cant use the app at all oi turn on the ACs. The last app said that I needed to start using this one, but this app doesnt allow me to do anything to the units. It has a menu for routines, but tells me that one of my 3 ACs cant be included, and when I try to set up a routine with the 2 it does say I own, the app has the temp control is in Celsius with no way for me to change it, and the buttons were not in English.
