Hi Xexvis,
Really appreciate your effort to post back, as for your concern, yes we get the screen for "Thanks! Your response was submitted. Submit another response", but I’m afraid completely bypass this and have a message post at the top of the form rather than being forwarded to a new screen is not available currently, we do understand your concern and to address it, you can feedback this to Microsoft FormsUserVoice, this is the Official platform to hear user’s great ideas and further improve the product.
Meanwhile, if you are willing, as a workaround, based on our test, if you want to submit the second response again without clicking “Submit another response.”, you can directly refresh this forms page.
Thanks again for your effort to share this with us, we will further improve the product.
Wish you a nice day!😊
Best regards,
Gloria
