Follow does not work?

Hello, I want to follow a friend, but when I press the Follow button it turns green with Following, but later it is just red again with Follow?
That friend can follow me.

No one has a solution for this?

Maybe it was a visual bug? Looking at your followers and your following list, it doesn’t seem to be an user who follows you and you don’t follow back.
Do you see that user in your following list?

Thanks for your response. No, he is not in my lists either. It seemed like he could follow me but that is not the case either.
He and I do get an email that we want to follow and with deny/aprove, but when I click on that there is nothing to see that someone wants to follow you.

I’ll pass this to a developer then.
