We are still seeing elevated numbers of 403 errors when requesting DM photos with a signed/authorized request.
I managed to get a signed request working in the browser (i can email you the full url with our tokens/keys, etc).
5 minutes ago it was working for me and I could repeatedly re-load the image. However, now I simply receive a “Your credentials do not allow access to this resource” error when trying to view in the browser.
Its strange because sometime it works totally fine, but the vast majority of the times since late last week we’ve been getting the same ‘not authorized’ error.
Would really appreciate any help on this. Happy to send you more information.
