Companion App workout Dash Drops during workout help?

When doing a workout on Zwift, the companion app workout dash come on giving me the watts etc. Intermittently the workout dash drops out and sometimes starts up immediately and other times it stays disconnected.
I have restarted the app and the problem persists. I am running Zwift on a Mac and companion app on an iphone. Both have all current updates. BTW it is only the workout dash that drops, the ride continues on zwift. Also the companion app’s other features are functional, again, I just lose the workout dash.
