Wifi Issues after update

I updated my samsung S9 last week and since then I'm unable to connect to the wireless network in work. Its trying to connect but the login screen is blank and there's nowhere for me to enter my id/password. When I open in browser its saying
Wifi not approved by operating system.

Any idea how to fix this - never had this issue until I updated to Android Pie......
