im trying to upgrade my wifes S21 ultra, when i enter my details it sess congratulations i can upgrade and gives me a choice of the FOlD4 or FLIP4. but when i choose the FOLD 4 i enter the details for my phone and i get the message: Error submitting the Grade of your device, please try again later. and i can go no further. this has been happening for the last 3weeks. i spoke to some on chat but she didnt seem to know anything about the upgrade programme, she said i can only upgrade to the s22 but that is currently unavailable on the upgrade programme. why does it it other me the FLIP and FOLD phones as choices then? what's the point of the Upgrade programme if i cant upgrade? id Appreciate a reply from someone at Samsung who actually knows about the upgrade programme. if there is no upgrade available i want to return my phone and close my klarna account as this has been miss-sold.
