Thank you for your replay. Yes, the Instance Geo is the same with our working area.
We were working hard with our support team to fix this issue. We've come to the conclusion, that it can't be a performance flaw. When one of our customers ist filling out a form, we can find her/him almost instantly in the contacts list.
*But the Dynamic Segments refresh exactly every 60 minutes*
Thats why it takes so long for the response email being send to the customer, because the dynamic segments are just way to slow.
Up to 1 Hour response time between interaction and reply is unacceptable for our customer experience. Until now we couldnt find any way to alter the refresh rate of dynamic segments.
Do you think there is a solution without rebuilding this with Flow?
