So just for clarity.  I use my mobile phone as a hot spot.  I have a tablet for gigs.  I have a laptop as well.  I use all 3 with mobilesheets.  My mobile has a big mobile broadband deal so I hotspot that (I don't have home wifi).  I also have another dongle with slow and expensive downloads.  

If I try to connect with the companion app from my phone without connecting to a wifi network, it doesn't even try to connect to anything, it just gives the USB debugging popup.  However, I can connect to the companion app from the tablet, using my mobile phone as a hotspot to connect laptop to tablet.
