Can't log in through iPhone but can on laptop

[user-removed]

I can log onto my premium account on my mac but not on my iPhone. When I try it reloads the log in with facebook page again and again. I recently updated my facebook password and this issue started. Haven't yet found a solution on here. Any ideas? Thanks.
