I wrote an excel add-in a while back that has been working for a little over a year, but stopped working the other day when Excel updated. The add-in writes text to localstorage, but I keep getting an error that says:
Tracking Prevention blocked access to storage for https://appsforoffice.microsoft.com/lib/1.1/hosted/office.js.
OSF.DDA.ERROR code 7000, permission denied.
I came across this stack overflow question from a few years ago and it appeared to be a bug in Excel, but I'm not sure if this is the case this time.
Are there any settings I can change to my machine and clients' machines to allow this add-in to work normally again?
