I can not import from a CSV file into my credit-card account anymore, what has been possible before. The account does not show up in the import dialog anymore. Reproducible: Always
I reported this problem a few weeks ago. It's the result of a recently introduced fix. It is possible to get round this by importing your credit card file into a temporary checking account. Then, select all those transactions, right click and select move transaction to... your atual credit card account. There is a full fix in the offing.
