How do you resume a print after pause during Advanced Print?

Say I want to switch filaments during a print. I use the Advanced Print and specify the height to pause at. When I do this and it pauses I have no way to resume the print. The space where the pause button was at is just blank. I would expect there to be a play button there but there is not. I can't see any other way to actually resume the print. 

Did you lose your connection with the printer? If so, reconnect using the Settings (Gears at the top right of the screen then Printers).

No that's not the issue. Definitely still connected. I have the maintenance options to extrude and retract and they still work. I can stop the print even.

When the Print started and I removed the USB cable once, I pressed the switch in the front to pause the print and resumed it, but not sure how I did it. You have to watch out because it is possible that the Printer resets and falls down. I think a long press is to initialize the print. A double press is maybe for the resume.

Thanks I'll give that a try but surely this cannot be the intended solution.
