Horrible upgrade - why’d you do it? – WoofTrax: Dog walk for charity Review

I use this app at least once a day, usually twice. Today I installed the update. The look of the app is completely different, stays frozen on the first screen no matter what “option” I choose at the bottom. Where is the map info from my last walk?! Where is option to select both of my dogs, not just the one? Can I get the previous version back?
