Hi, @Navski.
Welcome to the Roku Community!
We see that your Roku Mobile App is not running on Android 8. We're here to provide information.
Our official Roku Mobile App is designed to be compatible with Android devices running version 5.0 or later. To download the Roku mobile app for Android, you can visit the Google Play store directly on your Android device or access the online Google Play store through a web browser on your computer or mobile device.
If you're having trouble getting the Roku app to work on your Android 8 device, which is currently supported by the app, you may try to check if you downloaded the Official Roku App. Also, you may try to uninstall and then reinstall the app to see if it makes any difference.
For more troubleshooting, check out this support article: How to connect your phone to a Roku streaming device with the Roku mobile app.
Let us know how this works.
All the best,
Emman
