Could I ask for a little more detail on what your question is?
As far as I can tell, you're asking if your URL 'exampledomain.travel' is not loading in the editor?
And can I ask if you're entering this URL when going through the signup process, or whether you're just creating a new experiment from the project page and entering the URL, or maybe editing a previous experiment's 'options > editor settings'? Please try all of the above to see whether you can get your URL to load.
Hey there, I am also having the same problem and can answer your questions.
In the very first set-up process, when it asks you for your domain for the first time and nothing else, it looks like it's having trouble recognizing the new TLDs... Mine is conquer.today and I get the error message it is not a valid domain and cannot progress any further.
This is now a known issue, and we're working on the best way to handle these sorts of domains right now. We'll let you know here as soon as we have an update on this issue.
