A. 1. Close the app completely: Double-tap the home button (or swipe up from the bottom of the screen on newer iPhones) to view all open apps. Swipe up on the Reverb app to close it. Then, reopen the app and try streaming again. 2. Check for updates: Go to the App Store, tap on your profile icon at the top right, and scroll down to see if Reverb has an available update. If so, tap 'Update' to install the latest version, which may fix freezing issues.

B. 3. Restart your iPhone: Sometimes, a simple restart can resolve app performance issues. Press and hold the power button until you see the 'slide to power off' option. Slide to turn off, wait a few seconds, then turn it back on.
