1. I originally published a reasonably large (28mb) pptx file and it had a spinning object indicating it was still busy (all good), however I made some changes (from within powerpoint) and republished. With this 2nd update there was no indication of how the update was progressing. Is there a change in the wings for this?
2. With subsequent updates is the update merely looking at the incremental change or is it doing a complete re-save of the entire file?
