We have been using SharePoint online community site to create a site for are teaching staff, we have been uploading all sorts of file types (via the quick links web part ) but now are unable to upload PDF or PUB files. Any ideas?
Per my knowledge, PDFs are not well supported by the modern Quick Links webpart at this moment. As a workaround, you can upload a PDF to document library first, copy the URL and paste to the Quick Links webpart (last option - From a URL).
