If a user experiences some odd and unusual Dynamics 365 behavior, it could be due to the browser “plugins” that are known as Chrome extensions, Firefox add-ons, and Edge extensions alike.
Recently I installed AdBlock and Privacy Badger and found that I cannot effectively access Dynamics 365 / CRM without disabling these extensions. That seems to be logical: Dynamics makes a fair use of headers and cookies, both frown upon by privacy nut jobs and anti-ad advocates.
There are probably some other extensions that could trigger unusual behavior so, before blaming Dynamics 365 / CRM for not displaying your pages properly, try running your browser without any extensions or add-ons. The easiest way to do that is to use browser user profiles or incognito mode, both by default won’t load any extensions.
