Ipad 4 will not open with new update!!!

After new update unusable on Ipad 4. Tried shutting device completely down with same results of immediate crash when first opening. Tried contacting support before leaving review but links do not lead to place to leave information do forced to leave here with negative review. I liked this app in the past although not as detailed as I would like in some locations like when visiting Bolivia. If updated to work will change review.
