A. To improve the accuracy of friends' listening history, ensure that you and your friends have the latest version of the app installed. Encourage them to check for updates in the App Store. Additionally, try logging out and back into your account to refresh the data. Go to Settings in the app, select your account, and choose 'Log Out'. Then log back in.
B. If the issue persists, check your internet connection. A weak or unstable connection can lead to delays in updating friends' listening history. Switch to a stronger Wi-Fi network or ensure you have a good cellular signal.
