Thanks for your response! Yes, I chose the dragon egg and chieved champion (Greymon) but it didn't saved 🥲 how do I delete the data? Or would be better to uninstall and re install?
if you press the game's icon and go to the information, then storage and cache, should be an option "clear storage" the game would be fresh new doing this, if you find it difficult you can just uninstall and re install.
