Update: apparently there were issues with payments via Swedbank Pay, but my case is already solved. I guess it was kind of random, because I made two purchases on same day and only one of them had issues. I hope it can be solved for others.
Hello, I have same issue with a purchase I made yesterday 31 December. Order is marked as “on hold” in my account and didn’t get an eMail confirmation nor serial number. The amount was deducted immediately from my card, though. I contacted support some minutes ago. Of course I waited some hours in case it was a temporary issue, but that was yesterday, so I think it is something bigger.
