Devblog cross-website login session issue?

I've been having problems with Devblog recently.

For one thing, whenever I go to someone's blog with a hashnode.dev or custom URL, it doesn't seem to recognize that I'm signed in.

It has a button at the top that says "Sign In", but when I try to click it it shows a reloading symbol and then goes back to the button.

Also, I noticed that for it was taking a really long time for any custom url blog to load.

Has anyone else been having problems, or is it just me?
