To make sure my saves are transferred, once a new update is released, I keep the previous version. After I make sure that my saves and unlocks are there in the new version, I delete the older. Example: v28 comes out, and I have v27 installed already. I install v28 and open it to check my saves, gallery, CGs, etc. Once I know everything is there, I delete v27. That’s how I’ve always done it, but it should save everything if you have previously had it on your device. (sorry I went so long…)
