Cannot drag web parts on home page of Communications SharePoint 365 site.

I get similar errors when editing pages where I can drag web parts. When I try to drag a web part, I get the following error

Error: Error: Idle tracking cookie is missing.
at IdleSessionActivityMonitor.GetIssoCookieValue (activitymonitor.js:379:23)
at IdleSessionActivityMonitor.InitializeSettingsFromCookie (activitymonitor.js:363:57)
at LogIssoActivity (activitymonitor.js:130:26)

I have created another page and made it a homepage and can move the web parts but the only issue is that you cannot remove the title area from the new page. The title area does not exist in the original homepage but you cannot remove it entirely from any new page created. I see that you can make it smaller but there is still always a bar area where the title is that cannot be removed. How to hide title from Sharepoint page - Microsoft Community Hub. Note that I have also tried copying the homepage and rebuilding it however the copied homepage still has problems with web part drag and drop not working. 

So I guess that I will just have to resort to using a new page as homepage and live with the extra space in the title area that cannot be removed. At least with the new homepage, I can move web parts.

Thank you
