A. 1. Ensure you are logged in: Make sure you are logged into your account when adding items to the cart, as items may not save if you are not logged in. 2. Check for app updates: Go to the Google Play Store and check for updates for MAYD. Updating the app can fix bugs that cause items to disappear.

B. 3. Clear app cache: Go to Settings > Apps > MAYD > Storage > Clear Cache. This can help resolve issues with the cart.
