SUMMARY As several major German banks have updated their APIs, kmymoney can no longer retrieve account statements from these. This is discussed in several forum threads, e.g. https://homebanking-hilfe.de/forum/topic.php?t=26887 (in German). To support the new API, aqbanking is required in at least version 6.5.12beta (implying an update to gwenhywfar 5.11.2beta also). SOFTWARE/OS VERSIONS Flatpak version : 5.1.0 (confusingly shipping kmymoney 5.1.3)
Thank you for the information. Unfortunately, it is unknown to the KMyMoney development team who created and maintains this package nor how it could be updated. It would be very nice to see this being updated as part of the CI/CD pipelines and we're happy to work with volunteers on that.
Sorry for the misplaced report. I opened https://github.com/flathub/org.kde.kmymoney/issues/43 instead, closing this.
