@KewlCat @FelixDefrance @aeris It's possible they're rolling out a service-side change banning other operating systems with information sent by current versions of the app already. These changes are often gradually phased in for a small number of users for testing while minimizing how many users will experience issues initially so they can decide if they want to roll it out further. If that's what's going on then complaints being made right now are crucial including from people not impacted yet.
