Errors when saving bank account using Plaid

Please forward this to your IT department.  The Plaid flow for adding a bank account on xfinity.com is broken.  I got an error every time I tried to save my bank account info.  

I had the same issue with Edge and Chrome.  It finally saved even though I got an error.

I saw CSP errors, and this in my browser console:
