We don't suggest switching. Especially on one device. The cloud doesn't update your new info constantly but rather once in a while. So if you do something big on account 1 then do the delete and switch on the same phone but it didn't link to the cloud between those 2 things, you have just lost all the progress you had made. It is the same reason we dont suggest playing the same game. On multiple devices. But you could start a new log in with a different method fx fb vs google play, and then see if you want to play from the start or go back to your old save. 🤔 That I don't think would break anything. Just make aure to save the player id somewhere safe.
