Is this a pervasive problem? I spend 40 mins on a call with Apple support last week and they said it's a problem with Starbucks and McDonald's etc. wifi security and has NOTHING to do with Catalina -- only thing is I work in one of these places just about every day and things were fine the day before I "upgraded" to Catalina. I found out by accident that if you boot to Safe mode the pop-up window at both places will open -- you can then press accept and then reboot without safe mode and it holds the connection. Seriously stupid issue.
