They are all part of the same group.  I can't get a response from them either.  The scheduler is known to block people on a whim.

I did not get a reply from that group, until I used an old Gmail address.  Once I got approved, I switched to my Proton email.
Don't know if that is a thing or not.

Same problem here

I also seem to be blocked from “the group”. Wish I could figure out why.

They’re not currently taking new clients. So if you have seen them before they probably would schedule with you, but at the moment I’m assuming none of them are taking new clients.

At least one on that list is not with the "group" - Tandee... so if thats what is happening to more than one group perhaps you have an issue.

I know for sure both have responded to me.... I have seen Tessa recently and also Tandee.  Perhaps we have similar tastes
