Can't reinstall expansions

I'm a returning player, last time i played the game was about 6 years ago when the game was run on Origin. And in Origin when i changed device and logged in on my account i could re-download all my expansion together with the main game.

Today i wanted to re-download Origin only to notice that it got changed into an EA app and after i logged in, i noticed that i can download only the main game but not expansions, the app tells me that I need to buy them, even though i already bought them ages ago and played on my account before when it was still on Origin. 

Help would be appreciated because i used to own about 30 expansions and i don't really want to lose them.
