When in person, I rarely interrupt. But on Zoom calls, I'm accidentally interrupting all the time. I think it's the slight delay that's the problem. I end up mis-judging when my time to speak is.

Interruptions on video calls are also significantly worse than those that happen in-person, because the presence of a louder person's audio will often completely erase the audio of anyone who was trying to speak at the same time. At least in real-life, you can still catch what the quiet person said amongst the noise if you were paying attention.
