Changelly is not displaying live pricing for purchasing Lumens. How often does this occur? Is there a ticket process to see if something isn't working as it should?
I think there is a problem with exchanging XLM at present and I am sure they are on the case as I have just also looked on Bittrex and they are saying the same thing.
Hang in there
This is annoying. They don't even list the ticker. Could be a future update, but I think they have bigger things to deal with right now.
It'll be back soon I'm sure!
