I wanted to download an mp4 video from AWS (the link is private, sorry, but I assume the following is true for at least all mp4 videos on AWS as there was nothing special about this one).
Clicking the corresponding link worked just fine and I could watch the video in Orion. When I right-clicked on the video and chose Download Video in the context menu, no error message appeared and indeed the mp4 file was stored on my local disk. However, it was and remained empty (0 Byte), but Orion obviously considered it successfully downloaded.
I have enabled the preference to ask for the storage location for each download individually, in case this matters. Compatibility mode did not help; Safari worked fine.
