Indoor Location Mapping Tool Continually Fails

I was also having this issue and haven’t been able to fix it. I decided to add the beacons to a different mesh to see if that fixed it but in doing so I got stuck with another issue which I have spoken about here: "Unable to fetch your mesh networks" on iOS and Android App

One thing you can do, like Raphael suggested in that thread, is create the indoor map using your own app that you will have to program yourself following this tutorial: https://developer.estimote.com/indoor/map-your-location/
