A. Check your internet connection. A weak or unstable connection can cause the app to log you out. Try switching between Wi-Fi and mobile data to see if the issue persists. If you are using a VPN, try disabling it temporarily to see if that resolves the issue.
B. Update the app to the latest version. Go to the App Store, search for Yupi, and see if there is an update available. Developers often release updates to fix bugs and improve stability.
