Can’t even open the app – Vintagio Review

I had been using this app for 4-5years, but since last year they keep telling me to update it to work iOS 11. ever time when i start to open the app, even i update my iOS to 11.2 still can’t use, so disappointing. Hope you guys can fix it cause i really like this app.
