PTR Issues

I have been going in circles for 2 weeks maybe more everytime I try loading PTR no matter the version PTR 12.0.7. PTR 12.1.0, PTR 12.1.5) all I get is either no realms are currently available or a realm selection screen with only one option (Internal Alpha and it’s offline) I tried support and got told support doesn’t help with PTR and come to forums to get help from other players. So here I am can anyone help?

Mine is also incompatible right now. I used Check for Updates and Scan and Repair. Maybe Blizzard did an update and hasn’t pushed the latest version client side? I don’t know either.
