I have an Excel file that is an XLSM that I have shared. I can open it from my desktop PC by right clicking on it and selecting the option to Open In App and make changes and save it. When I attempt to do the same process from my other PC, it get an error stating the Last Modified date was September 27 and that I needed to either Save a Copy or Discard Changes. Regardless of which ever option I select, I am still getting a message stating "Excel is uploading your most recent changes . . " This box never goes away. I can again go into the File section of Teams and manually download the file and see the latest changes but I cannot edit it from the Open In App process from Teams directly.
If there is a way to purge the temp files from Excel, I am open to doing that as there are no updates/changes I need to save on this second PC. I have deleted Teams temp files, Excel temp files, I have even removed the entire Office suite but still getting this error.
