Please update or refund – KORG Module Review

Lately this app has been making my phone (iPhone 11 13.4 iOS) heat up when I use it.. which doesn’t seem to happen with iGrand piano.. I have tried reinstalling. Revised (5/12/20) PleaSe update or refund. After multiple times of uninstalling and reinstalling, the app definitely makes my phone heat up making my phone hot to the touch on the back! No heating problems whatsoever with iGrand piano or perfect piano or garage band.
