MAJOR BUGFIX
Thanks @kembond for validating the problem and for the idea fix. And thanks @batraD for finding this bug in the first place. Shout out to @Babar_Khan too for your patience.
I did a fresh install and was able to replicate the error. It was then easy to find the fix. Turns out it was a bonehead move on my part (like most coding errors) where I forgot to change the ST constants to the variables set on the new auth page. This was making the calls to getAccessToken and getEndPoint both not work. I have since fixed this and uploaded a fix. The updated fix has been verified to work. This should fix all the problems people are experiencing with their devices not showing up.
I know you are all probably wondering… why in the heck did I not see this myself. Well I made the mistake of forgetting to remove my hardwired auth variables so my installation was happily using a pre-validated set of variables. I have since fixed this too by creating a fresh install folder where I will always test future posts against.
I’m super sorry folks for any inconvenience this caused you all, but then again, this is free hobby code so I guess I don’t feel too bad. Anyway, it should be fixed now. I will be making further tweaks to the tile editor over the weekend. It is better but still has a few bugs and incorrect behaviors.
Please don’t hesitate to keep posting bugs here. And thanks again for everyone’s patience.
