Hello,
I am trying to upgrade an app on multiple devices. The devices I am using are Honeywell CN80s running Android 8.1.0. I need to know how to purchase in app purchases. Every time I try to upgrade the app I get an error saying "An error occurred while purchasing. Unable to process purchase. Please, check your internet connection and try again later." The internet is fine on the handheld. Any help would be much appreciated!
Thank you,
