Connection to XLAM file on OneDrive triggers "This workbook contains links to one or more resources..." warning

[freelensia]

Hi,

I have developed an Excel Add-In. The add-in is stored in C:\OneDrive\XJ15 Macros\Live\Freelensia Macros.xlam
Note that the OneDrive folder has been moved to C Drive and the add-in is stored there instead of in the Personal Add-Ins folder.

I have Excel connected to this add-in via Options - Add-Ins.

Now every time I create a new (blank) workbook, I see the warning:
"This workbook contains links to one or more resources..."

This warning is also there even if I open an existing workbook with data, go to Edit Links and turn off the Startup Prompt settings.

When I disable the connection to the add-in via Options - Add-Ins, the message goes away.

Why would connections to XLAM files trigger this warning? It is not getting any data from the XLAM file. Anybody with ideas to fix this, or at least turn off this message without having to disable connection to the add-in?

I use Excel 2016/2019 with OneDrive Personal

Thanks!
