If the screenshots have uploaded correctly, they show that web pages are being cut-off slightly at the top when an external link is open in the In App Browser. The pages and header / toolbar within the app work fine. The problem is with the In App Browser and nothing I found to try to adjust the display once the IAB opens has worked. I have only seen this problem on my samsung s8 test device, android 7.0. Other android devices, Samsung S7 and Google Pixel, are fine.
