Hey Yersiniosis
It can work visa-versa across everything e.g. Mobile, Tablet, Switch and PC :)
On your Steam version, you need to:
- Go To Settings
- Link Account
- Generate Code
(then on your device you are wanting your Steam version to link to)
- Go to Settings
- Link Account
- Input Code
(This will need to be done within a small time window so if it doesn't work don't be alarmed)
Then it'll ask you for which account you wish to choose (make sure you select your correct Steam version i.e. playertag is the best indication of this)
Then your Steam version will carry over to the device you wish to continue playing on the go with.
I've included video's we have done in the past as well :)
