A. 1. Restart the Roku App: Close the app completely by swiping it away from the app switcher. Then, reopen the app to see if the issue persists. 2. Check for Updates: Go to the App Store, search for the Roku App, and see if there are any updates available. If so, update the app to the latest version. 3. Restart Your Device: Sometimes, simply restarting your iPhone can resolve temporary glitches that cause apps to freeze.

B. 4. Clear App Cache: Go to Settings > General > iPhone Storage > Roku App. If there is an option to offload the app, do so. This will clear some cache and may help with freezing issues.
