I have been attempting to use the Flow Add-In for Excel (Preview). The problem I am having is when I open the Flow Preview, nothing really happens. It appears that, for a while, Excel attempts to load the Flow add-in, but eventually fails (leaving a blank preview window). If I right click in the window and try to reload, I get the same result. I have already tried to Repair my Office install via the control panel. Not sure what else to do. Anyone else have this problem? Suggestions for a fix?
I hope it's okay that I just add a bug to this thread ... Do you know why can't I log in to the Flow Add In for Excel with my Office 365 subscription?
