I have Google drive working fine on my AppleTVs at home just fine (Ireland) — and my iPhone.
I’m visiting my mom in France, I signed up with the same AppleID (ITS and iCloud), downloaded infuse 7, the pro version was already activated somehow however it’s won’t add my Google Drive (iCloud sync is enabled though).
Any issue how to get Google Dive in this AppleTV too? — I’m definitely using the same iCloud account…
