DND restapp not showing Idle screen display msg when DND enabled

When using DND restapp to toggle DND, LED works as expected, but there is no DND text displayed on the Idle screen indicating the phone is DND. There is a GUI opting to suppress this message, but I have that disabled. I can see SIP NOTIFY packets being sent to the phone to control the LED, but there is nothing in the NOTIFY for screen display. IIRC, this used to work.

There is an identical issue with Call Forward REST app, no idle screen message is shown when enabled.
