Can't access paid campaigns

I bought the game in 2024, made all campaigns without issue. I started playing them again recently but suddenly today I can’t access HOTS, LOTV and Nova campaigns.
I still have the achievements. When I go to the shop it tells me I already own the game, but I have ‘Purchase to play’ in the game itself. What is this ?

the servers are currently down, so most players can’t access arcade maps, see their co-op levels, or track their campaign progress.
