I have profile for each games in Armory Crate. As soon as we close the app, phone will enable 120Hz refresh rate automatically. Now, the issue is happening when I play games (PUBG) for long duration (30 mins or more) and close it then the refresh rate set to 60Hz and the option is getting greyed out. This is happening only after recent update.
Note: Refresh rate will set back to 120Hz when you come back to desktop even if the game is still ON at the background.
