If it's not clear, the Documents folder in question is not the one you might see on your desktop. On my device, the path to the Android data folder is /storage/emulated/0/Android/data. Similarly, the path to the Renpy_Saves folder would then be /storage/emulated/0/Documents/Renpy_Saves1) the guide is still using vxx while apk now use naming system ch4up3. Since the app didn't generate the folder of "renpy_saves" anywhere in my case, this make me wonder how should I name the folder to make it works in case I can just make the folder myself
2. I did install, give permission to write, and check my internal and external storage. There was no folder named "renpy_saves". Although there is folder named palecarnation.v43 in android data but the folder is empty.
3. I have no "renpy_save" folder anywhere. I try to copy the rpa to folder pale carnation.v43 in android data folder rightaway, or make a folder named "game" inside of it and move the rpa into it, both not working.
4. No folder named "game" inside folder palecarnation.v43 in android data. I tried to make a folder renpy_saves/palecarnation.v43/game in internal storage and move the .rpa inside. Not working.
I believe that the instructions may not be up to date - the folder to use there is indeed palecarnations.v43
See if that helps.
