The device I’m using is between IPadOS and/or IPhone IOS.
I would love to show you how I’ve done to give you a better visual experience, but I can’t access to post photos.
1.) I used an Ren’Py app for me to be able to access the game. I went into Mod Management, chose the option called, “Import Compatibility Mod” and clicked a rpa file. It did well for Step 1-3 DLC.
2.) I clicked a DLC wedding rpa file and it shows exactly what the notification gave me, “Compatibility Mod Import Completed; Imported dlc_wedding.rpa.” It said ‘Import Completed’, as it did say the same for the rest of Step 1-3 DLC.
3.) As I went into the game, clicked the DLC info, it showed me that the, “Cove Wedding DLC: Not Installed” while the Step 1-3 DLC is ‘Installed’.
