If I buy the game on steam, do I need premium edition for the mobile version too?

Am I able to flip between the mobile and steam version on the go?

From a post on Reddit (3 or so years ago):

Hello everyone!

As promised, I am starting the roll-out for the cross-device Premium feature that was promised in my original announcement.

I have just rolled out this feature for those who have purchased on STEAM (Only Steam for now, not Mobile).

Everyone who has purchased Melvor Idle on STEAM can now create or login to a Cloud Account to automatically link your Steam Account to the profile.

If you login to this same cloud account on the Free Mobile Apps, or the Web version, you will be granted access to the Premium version of Melvor Idle.

Be sure to login to Steam FIRST before trying, so the game can link your account. You Steam account can only be linked to 1 Melvor Cloud account, and it will be the first one you login to.

This feature will also eventually roll out for those who purchased on Android or iOS. I will post another announcement when this is available.

And the wiki page states that If you purchase the game on mobile, you will not receive a Steam or Epic key. If you purchase on Steam or Epic, you can play the Full version on mobile or browser.

So I guess you do get access to a full version everywhere when buying on Steam, but buying on mobile to get full everywhere has not been implemented after all.
