@candleleigh I had this situation with N26. But they appologized and returned access to my account, and gave 2 year free of charge subscription to N26 metal. I do not even live in Germany. And have not experienced any problem since (I guess they have whitelisted me in this routine check ). The reason for trigger I suspect was a cash withdrawal followed shortly after money transfer from another bank (legitim salary account).
Be polite, file a complaint to complaints@n26.com. It will take time. Remember that N26 is a real bank, and has to obey to Federal Financial Supervisory Authority (BaFin). So you have opportunity to involve BaFin in lack of getting support from a German bank.
+1 vote for having savings in a backup bank (or two) regardless if you are a customer of N26 or any other bank.
