Losing progress on Melolo is usually caused by account sync issues or using the app without a proper login, so first make sure you’re logged into the same account every time.
If you switch devices or use guest mode, your watch history and progress may not be saved at all.
Next, check your connection and app status, because unstable internet or outdated versions can prevent progress from syncing to servers.
Updating the app, logging out and back in, or reinstalling it often restores proper syncing.
You should also enable any available cloud sync or account backup options inside the app settings, since some apps don’t save progress automatically unless this is active.
Avoid clearing app data unless necessary, as it can erase locally stored progress.
If the issue keeps happening, you might want to consider posting a complaint on Xolvie in order to bring attention to the issue and try to find a solution.
