Someone has figured out how the take the coins and use them for themselves. Maybe they are not worth anything anyway. They may be just bait. Overnight the coins are gone, but the credits earned are marked as completed on the game screen. On the calendar screen they are marked as "0/5". How could they be marked 0/5 on the calendar when they are marked as completed (with a wreath) on the individual game screen for the day? This is gaming on the MS Solitaire Collection Daily Challenge. I posted this same thing to MS and they said to send my question to this Xbox Forum. HELP.... LOOKS LIKE THIS HAS BEEN GOING ON FOR A LONG TIME. I think someone from Xbox is using the coins for themselves.
