Why is Boomerang and VSCO not working in Oneplus 2? Both the apps won't open.

[AC Question]

I just bought Oneplus 2 and all the apps are working fine. But i just installed Boomerang and VSCO and I don't know why but the apps won't open. I uninstalled both the apps like a zillion times but it still won't work. This is bothering me and i need to know the cause of the problem.

Is Boomerang not an add on for instagram, do you have instagram? are you sure you're downloading the correct apps?
