I bought unlimited play on another device
Tap the free battles pill on the start screen, then Restore purchase.
My progress isn't on my other device
Sign in to iCloud with the same Apple Account on both devices. Progress follows you through iCloud.
I can't buy sovereigns
Sovereigns are kept in your iCloud, so buying them needs you to be signed in to iCloud.
I can't find the other device nearby
Both devices need to be on the same network, and the game needs Local Network access: Settings → Privacy & Security → Local Network → Battlefleet Duo.
Change my ad privacy choices
In the game, open Settings → Privacy choices. This appears where Google asks for consent: the EEA, the UK and Switzerland.
