Hi @ Jaime,
Could you please share a screenshot of the configuration of your flow?
what is the normal mode that you mentioned?
I have made a test on my side, the flow always work fine and never stops working.
Please check if you have turn off the flow so the flow wouldn't run when a new response is submitted in forms.
Please share more details about the normal mode and your flow so we could provide a proper workaround for you.
Regards,
Alice Zhang
