Excel Online Error with Addepar Data Import Tool
Since we are Mac users, we are forced to use Excel Online in order to upload financial information into the Addepar Data Import Tool.
For over a year, this worked without incident. Approximately, five weeks ago, we started getting the attached error every time we tried to upload data using the Generate Entity Master button.
We have tried multiple computers (All Macs), different browsers (Safari, Chrome and Firefox), uninstalling and reinstalling the Addepar Add-in tool, using files that had been successfully uploaded with Data Import in the past, and Incognito Mode with newly created user accounts --> All without success. We either receive the attached error or the "spinning wheel of death" which requires us to close out the open tab.
We have exhausted Tier 1 resources and were told that this is an issue for Tier 2 and/or Engineering. Addepar updated the Data Import Tool recently, but we are the only ones experiencing issues and has been trying to help but they have hit a dead end.
Any help will be greatly appreciated.
