Overbridge & SSL Big Six

Hi. I am not able to get overbridge to work with my SSL Big Six. The console works with all other plugins and USB audio devices except my overbridge devices. I recently added the Big Six to my studio and previously was running an Apollo 8 Thunderbolt. The Apollo8 is now running into the Big Six external in. Overbridge continues to wok with the Apollo8 but will not operate with the Big Six. I’ve filed tickets with Elektron, Ableton, and SSL with no solution identified. Is anyone familiar with this problem and is there a solution?
