Thanks for sending through all of this, it's really helpful!

We are aware of several issues regarding the import of Serato Crates, the errors that you are receiving, and how expensive it is on your computer to import large libraries.

All three of these issues are things we are prioritising over the next few weeks.

To help us further, could you follow this guide to turn on logs:

https://support.mixo.dj/guide/how-to-turn-on-logs

And try importing again. Then send us the files which will be in Music > MIXO > Logs.

Thanks again for testing this, and for general usage in the meantime, we recommend using smaller libraries.
