Princess1; This account already exists comment would only come up with google account if you maybe mistakenly clicked on create an account instead of login so when you type in the email address it’s telling you the account already exists.
The you unfarmilair with using the same apps on multiple phones/tablets may I suggest just using your google account on all of the when you register on any game or other no matter which unit your on at the time this way no matter which you play on all the accounts will always be linked.
Just keep in mind though that on most apps and games you can only be logged into it from 1 unit at a time so if you forget to log out of the game say from your phone and then go to your tablet and want to login it will get 1 of 2 messages being 1) You are already logged in. OR 2) your already logged in on another device, would you like to log out of that decive and lig in here.
Technology today is smart and if you play along with it and follow your Devices suggestions keeping everything linked to your google account you will be just as smart.
Hope this helps you.
If by any chance you have already created different accounts and you would like to be able to link them together as one then this isn’t hard to do at all, just follow my steps below: Presuming all your devices accounts are on the same google account which can be done as I have about 7 devices all linked. If there then you can add the same google acc to everyvdevice without wiping the other account and it will work.
- go to games or apps account settings and change both the email address and password to exactly match (the same as) your google accounts email address and password. Go to each device and checkbthose settings in the game.
Once you have done that as long as you are logged into your device when you want to play or access the game it will automatically log you in considering you click on Allow the first time on each device.
All sounds confusing but really it’s very simple,
