I tried to install the new update on the Gacha plus that I have, which is the play store version, but it keeps saying app not installed, even though whenever I tried to download it, it always asked me if I wanted to update the game, and I always said yes. I want to install the new update, but at the same time, I fear that I may lose my progress on my ocs, since I have already taken up an entire slot page.
You'll have to export your oc's to save them and delete the playstore version unfortunately. Since its not the plaustore, it won't update unless its the playstore version. So you'll have to uninstall the playstore version and install the itch.io version since they are on different platforms, it won't update.
