App and account

I was wondering how you save a game on the hosted games app, so It can be retrieved for the second instalment of the series.

I primarily use the apps and have bought the first instalment of the series. I was wondering if there’s a way to connect my account to the apps.
Thank you!

You have to type in your email at the end of the game if it’s available. Some CoG/HG series have this function from the get-go like the Wayhaven Chronicles but some have to wait for confirmation of the sequel before CoG update the app with a save game feature.
