App appears unsupported

Ive had this app since early last summer. About two months ago the display of who won prizes disappeared and it is now blank. Theres no point in trying to win a prize if you have no way of determining if youre a winner. You generally have to open the app let it freeze, force it closed and open it again before you can attempt to check in and win a prize. Monthly and weekly prizes have disappeared and there is only the occasional daily price. Beginning today, February 3, the app does not open, it immediately crashes. The above indicated problems are identical on my iPhone 6s and for my friend who uses the app on an iPad.
