Problems with IOS gamepaly

Iam using Chess App installed from App Store(IOS) in IPad. There were few game play features absent than from normal gameplay through web browser

1) Unable to make predictive move.

2) Chat not working when watching Chess Live Videos 

3) Options of Bug house etc are not at all show in chess live only standard game is their and can’t see open challenges unlike through my web browser(Safari)

I was not able to access learn-openings on IOS

I think the predictive move, called premove, must be turned on under settings.

To avoid these problems i use Android.not IOS

A debate that can go on forever hehe

Sure.

Thanks for report; checking on them! 

But i want to ask you guys.If i am buying a phone...shall i buy an ios or android

IOS
