I have an account with the german comdirect bank. I have three account (Giro, Depot and Visa Card). HBCI download with Giro works fine. HBCI for visa card results in error message, no lines found for this time span (German: Es liegen keine Buchungen für die gewählte Zeitspanne vor). Searching the internet, this has been reported several times. AqBanking itself seems to work fine. (https://gnucash-de.gnucash.narkive.com/yozYsI3D/fints-und-die-comdirect-kreditkarte) Some suggested to enter dates. I put in a date range ending in the past (01. Jan 2019 - 31. March 2019. The result was, that I got all lines AFTER 31.03.2019. I then tried from 31. March 19 to 1. Jan 19. I got the desired result list. For me, this looks like the date range given from gnuCash to AqBanking is just in the wrong order.
