The screenshot above shows a part of the new Interface when viewing a contact record. The screenshot below shows how you would navigate to the Advanced Settings.
Once opened you’ll notice that the system is showing the old interface with the old navigation bar. Selecting recent records, I can see the contact I had opened in the screenshot earlier along with a list of recent contacts.
The screenshot below shows the same record being opening in the old Interface. This workaround isn’t limited to records only as the recent views will also be shown and can be selected. So, using this method you’re also able to open views in the old Interface.
