Can’t get past the privacy policy – Jinvoo Smart Review

I am on an iPhone XR and downloaded the app after receiving my smart plugs from Amazon. When I load the app I click on Register and then the privacy policy pops up, I click on agree which turns the button grey and then the app freezes up solid. I am unable to continue as each time I try the app locks up in the same place.
