Hate this new "feature"?

I had this app this morning and I loved it but, a few minutes ago, it turned out to be "updated" and now it wont let me full screen videos AND when I try to press "learn more" to try to figure out why, it closes that notification and I cant do anything about it ?. Why do previously good apps have to turn into something SO BAD.
