Crashing – Quiver - 3D Coloring App Review

I wanted to contact app support, but it’s not available. I’ve been using Quiver in my classroom for a few years. However, the app won’t even load completely now on my iPhone 7+, so I’m sure it’s not an “old phone” issue. I’ve shut down the phone and the app many times. No luck.
