You can ignore those feedback reminder messages, we all get them, and as feedback is voluntary you do not have to leave any.
Which device are you using? If the app or mobile browser switch if you can to a PC / laptop and use Chrome, try from there, it usually is not affected so much by this common glitch.
Or, go to your feedback profile page, scroll to the very bottom you will see the link ....' Leave Feedback .'
