Hello All,
Thank you for the reports here and we apologize for the inconvenience.
We’ve identified an issue with our update server erroneously serving 1.8 Legacy builds when it was not supposed to, and have since corrected this behavior.
For those who have already been downgraded to Legacy 1.8 and wish to re-install Roon 2.0 on their Cores, please follow the 2.0 migration guide on our knowledge base, linked below.
1.8 Legacy is compatible with 2.0, so your Roon database should remain intact. If you encounter any further issues after following the guide, please start a new support topic and let us know, thank you!
