I have a Huawei P20 Pro and i bought the japanese game with a second account with japanese billing details. The game runs fine on its own but when patched, it will show the boot screen with the scarlet logo, then the same screen will swipe from right to left 2 or more times then it will crash to the home screen.

If i restore the original, it works fine again. Tried with the newest release.

there is also another bug, where if the game is installed for less than 15 minutes, it will auto refund the purchase too, meaning people have to buy it twice and play through at least 15 minutes before they can patch. Not sure this can be disabled by IrisMobile but would be cool to communicate it at least, if not. :) Will try to attach an error log, connecting my phone now to look up the files.

It is not a rooted device so cannot send a tombstone crash file as suggested by Uwabami.

Just realised that the instructions about finding an error log in “/ScarletStudy/IrisMobile/error.log” is stricly for IrisMobile and not DGS1 so not sure where i go from here and how i can help to make this working :(
