Quest 2 - Unreal Engine 5 Game Instance and Save Game Data nor working

Hey everyone!

Currently Im working on a VR game for both Standalone and PCVR with Unreal Engine 5, as the subject states, we're currently having issues with the Save Game Data and Game Instance specifically for standalone on the Quest 2. It all works perfectly on PCVR. We have already configured android permissions to read and write external storage, and distribution signing key. But now when trying to Add the Build through Meta Quest Developer Hub it fails.

Has anyone encountered any issues like this or should the Save Game and Game Instance be handled in a specific way for Quest 2?

Android permissions set on project settings
