Dropouts with Sonos speaker

I will preface by saying that I know Airplay 2 is not officially supported, but as I have had no problems with running Airplay 2 with my Roon setup-- (Roon Rock running from a NUC) a Bluesound Vault 2i and a Sonos One–this new issue makes me wonder if anyone else is having or has had this experience. I recently added another Sonos One for my covered porch. Roon had no problem seeing it as an Airplay device and adding it to the existing group, but since adding this to the setup I get frequent momentary dropouts. It did not happen when the Vault and the original Sonos were the only two in the group.
