PBS Kids activation issue

I purchased and setup a new 4th gen Apple TV today. I was able to successfully download and install the PBS Kids Video app. Unfortunately when I try to active the service within the app nothing happens. I click on the "Activate your Apple TV" icon and nothing happens. It should produce a login code, but it does not. Also, If I click on any of the other icons in the app nothing happens. I have attempted to delete and reinstall the app and I have updated and restarted the Apple TV. Nothing has resolved the issue so far. Also, I have been able to successfully install and activate the regular non-kids PBS app without any issues. Any suggestions? Is this happening to anyone else?

 

For anyone that is having this issue, I resolved it. It was a router specific problem. I have an ASUS RT-AC68U router. I had to switch off the built in "Ai Protection" options. After that, everything worked as expected.
