DELETE - a friend helped!
As someone who runs help forums for 20 years … Please don’t ask for questions to be deleted just because the problem was solved. Say how it was solved and let it stay there so it can help others too. Most problems don’t just come up once.
Also, I can confirm the issue. The CSVs are downloaded in some places, but not in others. I can replicate it in the earning section for example. This is server configuration issue and may or may not be intentional. Usually, a link in the browser will open in the same browser window. In order to make it an automatic download, the website has to tell the browser that, which isn’t happening here.
By the way: Technically, what you see in the browser window IS the CSV file. You can just copy and paste it, save it as CSV from a text editor and you have your CSV. Just a general tip. The SAVE AS … as described is probably the better solution in this case though.
