Hello! I'm here to help you with the issue of loading music in your Moises app on your iPhone. I understand how important it is to get back to making music smoothly. To assist you better, could you please provide more details regarding the error? For instance, is it during uploading music, or when you're trying to play a song?

In the meantime, let’s try a few general troubleshooting steps that might resolve the issue:

1. Log Out and Back In: Sometimes simply logging out of your Moises account and then logging back in can refresh your session. You can do this in the app’s settings.

2. Restart Your Device: A simple restart can often fix application issues. Just hold down the power button, slide to power off, and then turn it back on.

3. Reinstall the App: If the above steps don’t work, consider uninstalling the app and then reinstalling it from the App Store. Once you’ve done that, log back in and try to load your music again.

If these steps don't help or if you have a specific error message, please let me know!
