Unable to synchronize changes after editing file in Excel
In Signals Notebook, if an Excel document is opened
using ‘Edit in Excel’ in ‘Protected View’, the following error
may be shown on saving:
“UPLOAD FAILED. Your
file wasn't uploaded because your changes can't be merged with changes
made by someone else”
In MS Excel options, "Trust Center" settings, disable "Protected View"
for internet files.
MS Word does not seem to be affected, only Excel and PowerPoint.
