Octopi and windows phone

I was hoping to use my old windows phone as a 'controller' for the Creality printer, leave it permanently by the printer. I've set up octopi OK on a Raspberry pi 3d, and can control it fine from desktop w10 pc, fire tablet and android phone. On the windows phone, it gives the same full screen as the windows pc, but no icon to switch to the mobile view. It's running internet explorer, I can't find another browser. Thought it would re-purpose a redundant phone. Any ideas on forcing the mobile view?
