Symptom
After switching on "Enable the latest Viewing, Editing and History UI on Full Profile (With Non-Configurable UI)," the message does not pop up a Dialog Box but shows an error code 400 instead.
But if the option "Enable the latest Viewing, Editing and History UI on Full Profile (With Non-Configurable UI)" is not enabled, the error message is displayed as a popup as expected.
