Files app, certain files are grayed out.
In iOS 10 I was able to upload TCX files from my dropbox to a website via the Safari browser. In iOS 11 when I try to do this I have to go through the Files app. When I do this TCX files displayed faded and are not selectable so now I can no longer do what I used to do in iOS 10. From what I can tell the Files app distinguishes file types and fades out those it doesn’t recognize. Is there a way to get around this?
