Unity Remote 5: iPhone Connected But Nothing Happens

So the problem I’m having is that the Remote app doesn’t do anything for me. I am running an iOS build on 5.5.3 and even when my phone (iPhone 6s) is connected in the editor options, nothing happens; it just keeps telling me to select a device and hit play. Any idea what is going on?

Looking for an answer too

Hi, I switched into a new computer and although the device was recognized (iPhone 6S) nothing was displayed on the screed.
apparently installing iTunes did the trick.
