How do i get "do not show this again" settings to actually work on chrome and edge

1. I am using a pc with windows 10.

2. using chrome as the browser and do not want to switch at this time. Also same problem exists with edge.

3. have norton 360 installed

4. I am not using an authenticator app and never have.

5.as one example,  i checked the box on the xfinity login screen for "Do not ask this again in this browser" and every time i log back into xfinity for email i have to re enter a new verification code. Same thing happens when i try to log into norton and have to enter on the same pc the 6 digit code. 

6. I want the 2 step mfa, but if i check "for this pc browser to be remembered i also WANT the "Do not ask this again in this browser" to WORK!

7. on my iphone using safari or logging into from norton app everything works fine and no issues logging in and it isnt asking me for verification.

Help with #6 above please!

Thanks
