For months my partner and I have used the teaching table to practice and we have not been able to get the voice feature to work for the last few days. After I add myself & my partner to voice and click start speaking nothing happens. I can no longer click on anything and have to close the window, open a new one to sign back in. The red microphone does not appear as activated next to the url bridgebase.com on my browser window. Turning off my computer and restarting did not solve the problem . Any suggestions?
