Hello,
Ever since the most recent update, the chime is no longer playing when an attendee enters the waiting room (on both RingCentral Meetings AND RingCentral Video).
Now, when someone enters the waiting room, I only get a text notification on the top of my screen (no sound). Once the attendee has been admitted into the meeting, however, I do hear the chime.
I am running macOS Big Sur 11.2.3 on a 2018 MacBook Air with an Intel processor.
