Regional pricing not valid for EA App

Hello,

I am a Mac user and I have been using Origin to play the Sims 4 without any problems. The last time I logged in, I was forced to download EA App since I am using a newer operating system on Mac. So far so good, but Origin had a regional pricing, meaning that the prices were set reasonably in the currency I have (TRY) (I guess all the prices got fixed to the default only for the latest few expansion/game packs in US dollars, but the older ones still had the prices defined for my region). I cannot buy the older packs with the prices shown in Origin - I can no longer benefit from the regional pricing as all of them are now defined in US dollars in EA App. Is there any way to switch to the regional pricing? Because using a newer operating system (and not being allowed to use Origin) should not be something disadvantageous :D Thanks.
