Adding more details for this topic.Background –The static segment had several limitations; we initially had a cap of around 100 contacts. This seems to have changed now but due to this constraint and based on the recommendation, we created a separate record that would eventually connect to a dynamic segment. Issue/Challenge –Our main challenge today is the complexity around segment refresh times. Different types of segment refreshes at different intervals anywhere from 30 minutes to 24 hours depending on how the segments were created. For users this becomes difficult to manage the logic behind the refresh time as it is not intuitive. So, it's hard to remember which condition led to which refresh delay. This becomes even more tedious when users want to build a segment with specific rules but only need to use it once. We usually plan and build journeys several days or even weeks in advance. And another thing is where we use our static segment that we needed to be created for the automation with dynamic segments and then we upload contacts to it. Here the problem is that the journey start date becomes unreliable and hence the emails are not sent.  Possible solution - Ability to refresh the segment manually on UI.
