i can't accept friend's invites

Reason : i don't "own" the game

Real Reason : i have bought the game twice, first time on Origin second time on Steam.

So I obviously end up with less features thank you EA.

Fix : go back to Origin

Fix's problem : Origin may have all essential launcher features that EAapp don't have, it also bring me a bunch of other annoying bugs (like Tf2 cannot boot that's so fun)

Before I delete Tf2 from my steam account, does anyone here have a better solution ?

(Tf2 look cool on my steam profil I'd like to keep it if possible)
