Something else that might help.

Sorry, in the absence of additional information I provided what is available. Can't really help much on mobile as there isn't as much that can be controlled.
That said, having as stable of a connection as possible is best. Running on shared wifi can introduce potential reconnects/disconnects. So if that is how you connect, limiting data usage by other clients, such as streaming music or videos, may help.
Keeping background apps closed that might use data may also help, since other network connections can potentially interfere with the traffic to the site.


I know you can clear the app cache on Android, not sure how or if it is possible on iOS (it is an OS specific option, not app related).
The developers can only do so much with the client code. They probably can make the connection/reconnection code more robust but can't really account for other network related issues beyond that.
The site only controls the client app code, the last hop of the network path and the Live server code. Problems from the client device, through every other hop to the Live servers, can impact the connection. Even your device deciding to switch from wifi to cellular data, or in the reverse, can cause the app to suffer a disconnection it may not recover from easily.
