Double clicking the side button payment can not be completed
So I’ve been having trouble downloading apps, I’ve double tapped the actual physical side button but it just says “payment can not be completed” ( even tho it’s free )and I went into settings to try to turn it off and it never turned off, even if I turn of the “double click side button” in settings. Any help how to fix this or turn it off?
