I've seen other people with this problem and I decided to test it myself.
You can go through the normal process of creating a chat, but even after activating the chat, you aren't able to access it.
Let's say I made xat.com/CHATNAME, and I activated it. By going directly to xat.com/CHATNAME, I will be redirected to the groups page. The only way I would be able to access the chat to get my main owner, is if I add a ? after the link (xat.com/CHATNAME?). I don't know why this is so, but for the past week, I've noticed people having issues with it. Adding ? to the link is a simple solution, but not many people would know to try that.
UPDATE: After a while (for me it took 30 - 40 minutes) your chat is completely accessible without having to add ? after the link.
