I am facing permission issue while uploading as well as deleting font in SharePoint online. I am uploading here at this path -
<companyDomain>.sharepoint.com/sites/<siteName>/_catalogs/theme/15
Here when I am trying to upload fonts then an error occurred -
The document cannot be uploaded because different permissions are needed. Request the necessary permissions.
And when I am trying to remove fonts from theme/15 folders then an error occurred -
The server has encountered the following error(s)
fontscheme001.spfont
Access denied. You do not have permission to perform this action or access this resource.
When I am uploading at below path then font uploaded successfully.
path - <companyDomain>.sharepoint.com/_catalogs/theme/Forms/AllItems.aspx
My GOAL is to upload custom font for modern experience, am I following the correct process. If yes then why I am getting this permission issue also I have admin permissions(Full Control).
