Adobe Express reports 'Connection failed' during initial connections to Instagram or Facebook

Hi.  I have been fighting this issue for some time off and on for a couple weeks.  I have tried this in both the edge browser and by downloading the windows 11 app from the windows store.  In either case, I am unable to successfully connect to either my Facebook account or any of my Instagram accounts (via Facebook) from Adobe Express.  All the accounts are business accounts and are linked together in Account Center.  I can set up an initial connection so that in Facebook, Settings > Business Integrations, Adobe Express is active, but before I can move on, I get the Adobe Express message that the connection failed, please try again.

Under the view/edit in Facebook for Adobe Express, everything is checked, notifications are turned on and Only me is set for who can see the business integration.  I also see a numeric user ID in a field at the bottom of this screen.  Not sure what this is for, of if I should somehow be using it in Adobe Express...  

It is not clear if I need to connect to Facebook first, and then add a connection to Instagram, but in either case I run into the same problem.

I welcome any suggestions on how to make this work..
