Any thoughts? I've done the obvious, deleted and reinstalled app and restarted phone. I've got live games going on...

Try looking through these and see if any help or contact support directly. Hope it gets resolved soon

“Chess.conm couldn't authenticate server logging in via password through my iphone.”

i have this same problem! Can’t figure out what to do. I’ve tried deleting and downloading app, changed my password etc.. No problem logging in on browser. Just can’t on app
