iPhone 8 - iOS 13.3.1 wifi issues - connects but not transferring information

I am able to connect to my wifi network on my phone (Airport extreme), however, there is no data transfer. Instead my phone is using cellular service (spotty). To be clear - When I go to settings - Wi-Fi my network shows up, I have Auto-Join selected and it indicates that I am connected to that network. It just doesn't show up in the upper left hand corner of my phone screen, instead, my cell provider appears there.

I've done restarts on phone, router, etc. to no avail. My MacBook Pro and iPad Pro both see and use the Wi-Fi network just fine. I've also chosen "Forget this Network" and re-connected. It indicates there is a strong wifi signal and I am connected (on the Wi-Fi sheet). When I open Airport Utility I can see that my phone is not being served by the Airport extreme.

I've looked online for solutions. It appears to just be my phone that is having the issue.

Prior to upgrade to iOS 13.3.1 I had zero connectivity issues.

Any thoughts, solutions would be greatly appreciated
