“Error: MSS-5006” while connecting to Smartsheet from the Miro app.

I have a Miro board open and added SmartSheets to connect to.  When I get the screen with the Accept/Deny question and choose Accept, I get the MSS-5006 message.  I reached out to SmartSheets and they checked their logs and all was fine on that side, so now checking on the Miro side.
