Apple TV+ on Roku keeps “buffering”/freezing

Is anyone else having issues with the Apple TV+ app on Roku playing for a few minutes and then freezing? The spinning wheel appears as if it is buffering but it never moves in. It’s not my internet as I have VERY HIGH SPEED AND LARGE BANDWIDTH internet. I’ve tried deleting the app, restarting Roku, re-adding the app. Nothing has helped. Contacted Roku and they say it’s an apple app issue. This doesn’t happen with any other programming from any other app on the Roku device. Any help would be GREATLY APPRECIATED. I love the programming on Apple TV and want to keep watching it without issue. Thanks!
