Timeseries Sync not building from "Update" input dataset

We have a timeseries sync that is not triggering build from an input that has Update transactions. This results in in the timeseries being stale. When I force build then the timeseries runs the build and gets the up-to-date data. How can we avoid needing to do force-builds?

Hey could you check the build schedule for the sync run? I’m curious if the schedule is on input update or on some polling period.
