Not being able to add items to any list

So i tried updating a movie list of mine and i was unable to add movies to the list i tried a couple different times so i tried to see if a people list would work and it also didn't work with adding new people.

Anyone else having this problem?

I don't seem to have a problem. I just updated a people list without any problem.

I hope you find out what is wrong.

yeah i just tried both again still cant add anything
