Chess.com iPhone App

Hi,

I usually use the iPhone app to play my games.  Generally this works very well. 

Mainly I play blitz games (3min), recently I have found I am losing several games on time.  My connection seems to drop and despite making the moves very quickly it doesn't register on the game and more time passes. 

This problem occurs even though I have full connection to the internet (full bars on the phone).  I am guessing it is problem with the app connecting to the Chess.com server? 

Does anyone else have this problem? 

Not sure what to do about it, may contact the support team?

Thanks for any help.

Reloading (reinstalling) the app doesn't seem to resolve this.

Just played another game, had full connection to the internet the whole time.  When I make a move there is a delay before my opponents clock starts and I lose an addition 3 seconds or so.
