Seems like it would be a useful app, but unfortunately it doesn't load anything. Just displays blank black screens. Tried it on 3 android phones and 2 different Samsung s8 tablets all blank and black. Won't load any content. I'll update my review if I can get it working later

Normally a great app. Currently there is an issue. I am asked to validate my email for more content. When I attempt to do this, the app crashes.
