Anyone else experiencing app login issues?

My guess is everyone. The app does not seem to be connecting to the server for anything-- points earned update, refreshing the app, looking at the store, etc.

Shlomod, you might try login again-- the app is crediting silver (including the silver not credited yesterday), so it's possible that the connection has been restored to the phone app.

When trying to "top-up" on the "5 Gold Infinite Plan," does anyone else's payment field say "null?"

Mine says same

I do not remember if it said that when I bought the top up

I do however recommend you take a pic or screenshot after purchase.

Since mine shows nothing in history and I showed proof to support

Mine, too, has always said "null". Mysterious.
