When you check your following and try to go to a different page in the following section it says “error in / application”. When I change the URL it fixes it and leads me to a normal page. Turns out that when you try to go to a different page it leads you to a URL that does not exist. The URL that the button directs you to is
https://www.simplerockets.com/Following/Posts?p=2&t=0.
But the Posts thing is the thing that bricks it all. It is supposed to be
https://www.simplerockets.com/Following/?p=2&t=0.
Idk but should the website provider fix the redirect?
Btw this bug is not present within the SP website.
