we have used modern controls in the new form canvas power apps and we have used submit button and it worked before but now its not working but there are no errors. but same form worked fine in production settings, same now not working.
I would appreciate if we have any references for the same in the context of modern controls related stuffs as per your kind suggestion as it would be helpful to plan.
the issue you are facing is more or less caused by the modern control itself
they are still in preview and not there to be used is productive apps as of now. i and many others (even microsoft) dont recommend to use them already because they are not ready to be used. that they have worked in the past does not mean they also work tomorrow or another day.
do yourself a treat and dont use them, stick to the classic ones as of now because there is no solution to buggy modern controls
if my answer helped please mark as verified
cheers
