I can't purchase any Sims 4 packages during the mid-summer sale - I can only buy the bundles that are prepared in advance by EA. The app says that there is a problem updating the cart. I contacted the live chat, and they said that it is known (no solutions) - but so is the sale.
They told me all kinds of solutions on my end, even tho I repeatedly said to them that it is a completely technical problem with their EA app. They keep repeating that I need to change my payment method or contact the bank, but they don't understand that it is impossible to add to the cart at all, and the cart is empty. I can only pay for what is not on the so-called discount or for their pre-made bundles
