I updated my IOS to the latest version and seems like this issue is gone.

I encountered this problem as well (iPhone 11 Pro), but when I installed the software update it fixed the problem.

Hello, I was experiencing the same problem. What I did was updated the device to version 13.5.1(latest update) and was able to sign-in to iCloud. Hope this helps.

I reset my password on my safari browser and then signed in again on settings and did the the two factor authentication and it worked after that. Hope that helps.

I turned my phone off and then back on and that seemed to reset it

Update to IOS 13.5.1

I was having the same issue, updated, got the pop-ups and entered my password. Boom.

Fixed.
