Interrupts for forced upgrade that doesn't exist – Auction.com - Homes for Sale Review

Every time I open the app it gives me a message that there's a new upgrade. The only way to get rid of the window is to agree to the upgrade but when you go to the App Store there's none there. The only option is to "open". Annoying, and has been going on for months.
