New iPhone X working, but Apple said that it is not activated
Hello to everyone. I got a gift - new iPhone X, at&t unlocked (Mqct2ll/a, but works fine here, in Ukraine). I activated it, updated to newest firmware and all seems to work fine - FaceTime, iMessage, Find my iphone (checked from website), calls and messages, BUT when I try to check my warranty and purchase date on official Apple page it says that iphone is not activated. Same says unofficial imei checkers. I have activated my iphone 2 days ago. I tried to erase and reactivate it, I register it in iTunes on pc, still no luck - all checkers say that it is not activates. Who had the same problem or have any thoughts about it?
