Can't upload font to Creative Cloud - Processing failed
I'm trying to upload a font I'm using in an XD project so it displays correctly on other devices. When I go to CC > Manage Fonts > Add fonts to Creative Cloud and try to upload the font there, it says 'Processing failed' but gives no indication of what the probelem is.
It's a pretty standard, single-style OTF font and I don't have any problems using the font in any applications, the only problem is trying to upload it to CC.

Does anyone have any idea what the problem could be, or even if there's somewhere I can find a more detailed error message?
