Yep, I ensured I was doing that to no avail. I followed your YouTube hotspot video which didn't work either. I also went and started back at "square one" using all of Chord's video tutorials to ensure I was doing things "right". Needless to say I look at the Config Tool Pin with great disdain now. Glider seems to be a no-go. I tried to go back to 8Player but now it's incompatible with my old 4th Gen iPad which cannot upgrade to iOS 11.
So I went over to my Android tablet, a Samsung Galaxy Tab S. This worked fine as well pre Poly update to version 1.0.10 or whatever it is. Now, no success either. The closest I got was installing BubbleUPnP and could get Poly recognized as a Renderer. However, I could not get access to the Poly SDcard as a source. I'm not familiar with a Bubble so perhaps I'm missing something or need full unlocked version? Only reason I tried Bubble is Neutron will not see Poly any more.
It was 4 hours spent last night with no success. At one point I was seriously thinking about returning Poly. But if I do that, I'd probably want to get rid of Mojo too. And the expensive case that holds them together. Then I think about the eventual release of the GoFigure app, and more firmware fixes Chord are surely working on, which I don't want to miss out on in the event these do make MojoPoly the AmpDacDap kit it was "promised" to be.
So MojoPoly sits in its designated spot in my drawer of audio stuff until that day comes. Frustrated yet hopeful.
