I can confirm that all is as it should be.
A post was split to a new topic: Unable to follow blog
Here is a Federation issue from @gendor regarding turning off Federation on Write.as:
I tried to disable federation on my blog while I was busy importing a bunch of posts and didn’t want to spam everybody’s timeline. I unchecked "Federation
@firstname.lastname@example.org"and clicked “Save changes”, but it kept on federating, and when I refreshed the customize page the checkbox was checked again.
When I try to subscribe to my blog, it shows that I have sent a follow request, but I don’t know how to approve the follow request. My blog federation is @email@example.com, but I don’t know how to sign in anywhere as that identity and approve follow requests. I didn’t think I would have to, as the blog is public. Any guidance?
