A week ago my card stopped working suddenly. When I opened the bank app to check the balance I found that my card is not listed there - as if I've never had it (the linked account was intact though). It was a holiday so customer support responded with "if you don't want to block your card - come tomorrow at 9AM". Only after a few hours a warning appeared in the app that the bank currently has issues with some cards.
