Hi Walter, thanks for the prompt reply.

I'm on iOS 18.1 and was using Dropbox 432.2.4 when I got the error about the missing file extension. I've since updated the Dropbox app via the App Store (to the newest version available today), and now the error has changed.  Please see the screenshot attached.

I haven't seen the error for file types other than ".mp4"…but I haven't tried many. It seems to be working correctly for smaller things like ".txt" and ".md", and .jpg/.png files.

Thanks for the screenshot and the additional info, AC3EE963B1BF.

Have you added your Dropbox files to your Files app perhaps? And if so, are you able to view the videos from there?

How about if you save them to your device?
