I've been facing issues with Samsung UK webstore, constantly get "something went wrong" error at the checkout stage. I gave it a week and tried again with a different Bank Debit card and still get the same error.
It's a shame Samsung can not fix its payment gateway, the single most important feature of any online store.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
One Ui 5.0,Android 13 .
