Look center left on the "Command Ribbon" you want to toggle off. You will see a button that says "Full Screen Interface". Try clicking on that and you should get rid of the ribbon and your lower taskbar. I cant remember how to get it back up but ARC may show a popup with how to get back to normal view when you toggle it off. Have fun!!!

It is already in full screen interface mode. Even if I go into preferences and check full screen, that only removes the lower taskbar making little difference.

Sorry for the bad advice.

It’s holiday so I took care of this in my spare time. It’ll be in the next update

That's brilliant. Happy holidays.

Okay, it's ready for release soon. I think a few more things are getting worked on, so the release should be in the next week or so. It's a year-end update, so I believe there are more changes than usual.

It'll be in the next release - apologies for the delay. Now when you view the full screen, just press the X to close full screen

I have checked this feature in the new release. I get a white ribbon at the bottom of the screen when in full screen mode. Is there some setting to remove this? Also there is no toggle button to make the old top ribbon appear and disappear - not that it matters to me but it would mean every user has to resize their mobile interface for full screen mode.
