Hi @Vincent_Yeung, @Brett_Speller:
Build 202 of Roon fixed an issue with identical symptoms for some other users. Could you try updating to the most recent Roon build and see if that fixes the problem? You should be able to just download and install from https://roonlabs.com/downloads.html over your current install.
Here’s the thread from the other case: 1.3 can’t get beyond animated logo [fixed]
Please let me know if it helps, hopefully we’ve already fixed this.
