Hi, Thanks for replying. I was just typing… I’m indeed using TTN (and not TTI), thus via https://www.thethingsnetwork.org/ . And for configuration my gateways on the TTN side I use https://console.thethingsnetwork.org/gateways. These still use the V2 version of the stack, like you state at the end of the message 
I also see your statement regarding upgrading to the TTN V3 stack, I’ll try that using the documentation at: The Things Network upgrade to V3
(and of course watch the opening keynote :))
I hope the documentation on TTN will also be updated soon (which I can understand takes a while on the community driven TTN)
Thanks! I’ll let you the results after taking some time for adapting to the changes.
