Thumbnail not generated when attached the photo from mobile which is offline supported
By using Attach Content Control, I can add a photo to the page from my mobile phone, but the thumbnail is not shown as expected.
From the clipboard, I can see that the thumbnail of the attachment is always `pyTextThumbnail.svg`.
On the other hand, from the desktop channel, the thumbnail can be generated correctly.
My question is:
Can I also generate the thumbnail from the mobile?
