App or blitz online, never seen such need of network resources :-(

Either I play on Iphone or blitz online there is often lag issue, regular disconnection during a game. I do not understand how this applications are written. I can watch heavy videos, download huge files, get emails and everything else that eat a lot of networking bandwith without too much problems but the network needs for chess.com apps is going over the top.

So I do not know if it requires a large bandwith or if the apps protocols have issues but it is really frustrating to see my time left going down so fast or just get disconnected while all other apps are running well.

It was not such problematic back end of 2014. I tried many things that you can read here on forums (reinstall, delete cache, etc..).

Very disappointing and frustrating.
