Cannot download Roon 1.8 - Is it due to Mac OS update to Big Sur?

Please help get my Roon working on my Mac mini…

I am running a Mac Mini running Big Sur 11.1 and was able to install Roon 1.8. Initially Roon Radio was not operating but Roon fixed that in a few days. I’m afraid this may not help you technically but maybe will help with your search elsewhere. If I had it to do over, I would have waited to install Big Sur. I have a new Yamaha integrated amp with built in DAC which is not fully compatible with Big Sur. I’m waiting on information from Yamaha before installing their current software.
