Same experience here until I unpaired and reinstalled everything - now it's much better.
 
I really look forward to app thinning. Really hope a lot of apps can be cut down on space needed. For now Facebook Messenger takes up 107 mb for such a simple app, really looking forward to how small it can be.
Probably the same, just because Facebook is terrible. I've seen some users with 500Mb. Whatsapp and Facebook should be burn in digital hell.
