Remote Music Controller on Web

I cannot figure out how to use this app. I have downloaded the player as controller on both devices and I have no idea how to actually use it. Would love some customer support and would be happy to leave a stronger review if I can get it to work.

I tried to give this app developer the benefit of the doubt after reading an earlier remark that slammed the app as “don’t waste your money”. I totally agree all this developer does is “collect” $.99 from consumers knowing “no one” is going to complaint to Apple about $.99 because who has the time. This app is one of the worse I have seen for what it claims to do. I used an app called “tango” (discontinued) in the past and this app can’t touch it with a ten foot pole. And yes I am going to ask Apple for my $.99 back for this crap! DON’T BUY!

Doesn’t work on older devices as stated because it is only iOS 10 or higher and it looks like they spent 2 minutes designing the UI
