If youโ€™re confident youโ€™ve found a bug, youโ€™re welcome to directly report it on the issue tracker. But I do not use Windows as a daily driver, so a PR with a fix would be even more appreciated. :slight_smile:

Should I use the uh โ€œDeveloper Tasksโ€ issue type? Iโ€™m not sure if this is a Windows issue exactly, at the moment I canโ€™t test with Linux. By the way, AnkiDroid also fails to fetch the database; it says 400 but this time thereโ€™s no error on the server side. I would look into the issue myself but at the moment I just canโ€™t afford to build Anki :pensive:
