Android Chess.com app

Dear Sirs,

How is Chess.com app for Android tablet functioning? What is the difference between my normal subscription and the app for Android tablet? Does it not require internet connection or what is the exact difference technically?

Thank you for your help in advance.

Best regards,

The app doesn't have all the features of the site but the subscription on the site covers those features the app supports. Most of the features will require internet connectivity, except for the play vs the computer option and I think the Tactics option may cache some tactics and go into unrated mode if you don't have connectivity.

Thank you.

And can I use the subscription on the site via tablet as well?

Yes.

Thank you.

Installation failed with error code 504 on my android mobile device. 

I used it a lot in past but uninstalled it for some time. Now it is showing this error for app installation. My account is still active and I can play in web login. Kindly suggest remedy for app installation. Thanks.

Top search for that error suggests clearing the Google Play and the Google Service Framework cache and data, then try again.

Is there any way to contact chess.com from the android app? I use a PC but many people only use the app.
