We "publish" reports as Word documents via SharePoint.
Here is one: https://healthwatchbucks.sharepoint.com/:w:/g/EdLTxsEk5v9HpO0KLE9pCX0BcDOg-7mFW1PXE3hiwnVywQ?rtime=IO9HdpFK3Ug
On a desktop browser the formatting is exactly as intended.
In a mobile browser, this is not the case. For example, the "invisible table" formatting the title, is visible and the images have been moved outside the table.
NB In the live document, I've marked the two images as decorative using the accessibility feature and they no longer appear in the mobile viewer. So, that's interesting.
The process is completely opaque to the user but it's my understanding that a setting on SharePoint decides what to do when a mobile viewer is needed - is this something I can tweak or is it simply something I need to report upstream?
