Social media not updating
I am in Sri Lanka on holiday using wifi. Facebook and Twitter are barely loading new posts in my timeline/newsfeed. I will get one or two new posts. Then the rest of the posts displayed will be hours/days old. My wife who is using Android is not having this problem on the same wifi networks. Is there a way of deleting all this cached data so just new posts appear in my timelines?
