Hi Omar,

Did MIXO upload all of your tracks to your cloud storage and are they all showing green dots on your first computer?

You can try Settings/Debug -> Reset LOCAL on your second computer.

You can also try Settings/Cloud -> Force Sync Check on both computers. This might resolve any sync issues.

Failing that, you can try Settings/Debug -> Re-Sync This Library on your primary computer. This will delete all your synced data and re-sync your library.

Here's some useful info:
