Hi Sagi,To answer your question, no, the segment will not exclude
everyone that was originally in the segment after the update. However,
the segment will begin to qualify users based on the new rule, from the
day that the segment rule was updated and modify the population
accordingly.That's why the recommended approach is to always build out a
new segment instead of modifying an existing one to eliminate these
ambiguities.Hope this helps!Thanks, Nikhita
