I have created a custom function in the Excel office add-in and it's working fine with the local network, edge browser, and Mac but in Mozilla Firefox its give the error which is "#name",
I don't know why but it's happening only at Mozilla. I have used a shared run time environment for custom function It worked fine with the local host but when I used the server manifest file it showed #name.
i have used Set Name="SharedRuntime" MinVersion="1.1"
and i am getting Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://sfjlemon.ifour-consultancy.net/functions.json. in the console.log.
