I've bought Pathfinder Adventures on Steam when it was released. Owned the Android version for some time already, so I've synced my accounts with Android one being the main account. I then redeemed Pathfinder Ambassador rewards on Steam, and everything seemed to be synced perfectly - parties, progress, purchases.

 

The only thing not working properly is the "Rise of the Goblins" campaign. In my Android account it's shown as not bought (price is shown in store, "Buy" button is white). Yet I have access to Goblin skins and characters - same as in my Steam account. I can even start a "Rise of the Goblins" campaign - but it won't sync between accounts.

 

Valeros's Tale, bought through Steam, appears as "bought" on Android too - and this adventures syncs normally.

That seems to be known bug right now.  It's the same on iOS as well.  The in-game store isn't aware you purchased the content, but the rest of the game knows when you have a license for the Goblins campaign, and will happily let you play it.

 

The store glitch can be safely ignored until the next patch rolls around.

Yep. This has been round the release of Goblin campaign. The Main problem is that parties Are not synced between platforms so you have to comple each party with the same platform and not allowed to jump from one to another during the campaign.
