Just about every video call has this phrase.
If you think about all the video conferences that you have participated in since the onset of the pandemic, certainly the most frequent phrase that has to take the cake is "You are muted," or the variant, "You are on mute!"
Even when the pandemic is in our rearview mirrors, we will be having virtual meetings moving forward. Perhaps we'll all get better at it and the "You are on mute!" will be only in our memories.
I suppose the next most frequent phrase was/is, "Can you hear me now?"
