Hi,
I have recently attended Klaviyo Growth Webinar regarding the Sunset Flow and have created one following the instructions.
The flow is tied to an unengaged segment populated with unsuppressed and unengaged accounts, and have been back populated (experimented with both back-populating options - giving each circa 24h to take effect), yet the entire original segment of 700+ accounts is skipped for some reason (Email cancelled) and it seems to be working only on accounts added AFTER it went live, regardless of the back populating selection.
What am i doing wrong?
