Below the support answer from KeyCDN (from Roger):
The cache is bypassed if any of these plugins is used:

Otherwise is the cached version delivered to the mobile user.
David, thanks for your clear description how to do this in another post. This does remove certain elements. For example the filename ‘Maori Club (taiaha) (A$2,800).jpg’ turns a caption ‘Maori-Club-taiaha-A2800’. Can you tell me which characters are being preserved? That way we can change the way we name the source pictures.
After I created a new Superadmin the TFA option was not available in the admin menu. However, after posting I debugged some non-related errors and TFA became available. I was not able to recreate this glitch. Sorry! Maybe you can delete this post.
