How can I cancel all of the job that summited or pending in one time? Someone help me pls.

Hey @Akharin Sukcharoen , in the dashboard (front page) you should see a tile for all runs in progress. There should be a button to cancel all. It can take a while though depending on how many you rhave

I can't find it but thank you for your support.

One second I need to start a flow to reveal it

I think my Prefect version is lower that your that why I can't find them. Thank you for your support.
