I am trying to change the favicon for a site in SharePoint Online. I have seen how it is possible to do this by modifying a master page. However, with SharePoint Online Microsoft was recommended not modifying master pages as it might (will) break things when they push automatic updates- or it may just prevent auto updates, I'm not sure which, but either scenario I want to avoid.
Is this possible? Is there a file I can just replace somewhere on SharePoint Online? Could someone show me that path, if so?
