I have found that if the meeting is actually quick (sub 20 minutes) rebounding is not as difficult. When the "quick meeting" turns into a check in + "do we have time to talk about..." + any other number of meandering paths a meeting can travel down, I'll have a hard time getting back into task mode.
Something that helps me is to take a walk right after those meetings. Helps me reset when I get back to my desk.
This particular streamer is terrible. There are plenty of great ones; dont lump them all together.
