Hi again Mitchell, since my last post a few hours ago I have been trying various things etc. Like I said earlier, if I reset the Edge browser and clear search history under those "three horizontal" lines (Bing opening page) the OneDrive works again without signing in! I have found out today just by clearing the search history (without resetting) does the same! After awhile after using the browser I have to it again!
Unsure what's causing this!
