Problem with loading obb files

Hi! Have you also tried uploading the OBB to the application folder manually to check that it is working?

Remember that the app’s package folder under Android/obb/ (for example Android/obb/com.game.name ) is only created after the APK is installed once; trying to send the OBB before that will fail

This usually happens due to incorrect OBB path or storage permissions, try placing the OBB manually in  and make sure SideQuest has full access.
Unrelated, but similar to how people research companies hiring with workday certification before applying, double-check compatibility and file structure for Quest 3s specifically.
