Help! How can I revert to Roon 1.8?

Roon 2.0 update has been a disaster. I sometimes have no Internet connectivity where I live and none of my remotes are working. Moreover, ARC continuously says syncing to Roon Core but to no avail. How can we go back to the previous stable release?

OK. So I need to remove the core software from my Synology NAS. Where are the Synology NAS core files? What happens to the database?

I found this link to v1.8 for Synology at least RoonOnNAS – Verwende dein NAS als Roon Core

This is a huge problem.
