Went to the Google Play store on all my devices (Phones/Tablets), not listed went through Wondows web to Play Store (Not compatible with your devices). I’m not in a foriegn country, all devices registered in US.
Went to APK stores, all failed to install on any of my devices.
ARC is for phones and not tablets, tablet support has been mentioned as coming at some point. Also, devices must now be running a minimum of Android 9. You will want to update your Tablet to the standard Roon Remote 2.0.
