One of my users encountered a problem when using dropbox from my app from an iPhone: https://github.com/johannesj...
Actually, I think this may be this issue: https://github.com/angular/angular/issues/37133
There's a solution posted there. Can you try that out?

Thank you for the very quick response! Unfortunately, if I add a param to the request I get a 400 error:
`GET https://content.dropboxapi.com/2/files/download?ngsw-bypass=true 400 (Bad Request)`
And the body says:
Error in call to API function "files/download": Unexpected URL params: "ngsw-bypass"
Nevermind. I just figured that this is supposed to work as a header field as well. I get back to you once I've tested this.
Setting
'ngsw-bypass': trueas header won't also work unfortunately as I get a Cross-origin error then... Any ideas?

I see, thanks. I'm not too familiar with the underlying issue here with regards to why Safari is rejecting or corrupting these requests, but looking at the proposed solution, the Dropbox API certainly doesn't expect any extra parameters or headers. (I'm not sure why this is necessary anyway since this seems like a client issue, not a server-side issue; it doesn't happen in other browsers, for instance.)
In any case, I don't know which specific CORS error you're getting, but the Dropbox API does offer a few other options for formatting requests that may help workaround this. You can find information on those options under "Request and response formats" in the documentation, in particular in the "Content-download endpoints" and "Browser-based JavaScript and CORS pre-flight requests" sections.

...Hi johannesjo,
Take a look on the documentation more carefully. The query must be POST, not GET!
Hope this gives direction.
