A. 1. Check Your Internet Connection: Ensure that your Wi-Fi is working properly. You can do this by testing other apps or websites. If your connection is slow, try resetting your router or moving closer to it. 2. Close Background Apps: Double-tap the home button (or swipe up from the bottom on newer iPhones) and close any unnecessary apps running in the background that may be using bandwidth.

B. 3. Reinstall the Roku App: Uninstall the app by pressing and holding the app icon until it jiggles, then tap the 'X'. Reinstall it from the App Store to ensure you have a fresh version.
