Hello I would like to use `preview expect no changes` in com

Question

Hello I would like to use `preview expect no changes` in combination with to confirm that no changes will happen in `prod` when I enable a feature flag in `dev` This is mostly successful apart from which always detects an update even if the code has not changed regardless of whether the tasks are stopped Is that the expected behaviour I ve pasted the code in the thread if helpful
