I’m glad I’m not alone with this, it just happened to me and I was really confused. Same behavior as you described on kevin.rocks on iPad, using Firefox and Safari. As soon as I logged in, I was thrown into a loop that refreshes the page every second.

Do I understand you correctly, other instances don’t behave like this? In that case I will probably go elsewhere until someone finds a solution.

Edit: that’s not supposed to be a threat or tantrum, I’m just considering workarounds.
