I just bought touchless app awhile ago on my GNote 5 to disable the ads.. I was able to set it up correctly and completely. I reinstalled it on my Xiaomi Redmi 4A after a few minutes but I saw that the disable ads option is still there. Does that mean that I have to buy the app for each phone I got? and/or buy the app every time I reinstall? Also, when I try to set it up on my Note 5, there were no issues.. but setting it up on my Xiaomi redmi 4A is not working for me.. I keep getting stuck on this window: The touchless chat window does not appear... so I cant swipe it away and I also cannot click next as its grayed out.. I cant do anything about it as all other options/settings I tried leads me to this same window.. Hope you can help.. Thanks.
