Just keeping this thread relevant and at the top of the developers list of support items.  I still cannot access Venmo via Quickbooks and get an error 103. 

My log in credentials are correct.

I can use them to log into Venmo directly - however connecting to Quickbooks has been unsuccessful.

I tried just a few moments ago.

I don't have time currently to try to "Phone" support.  But I'm hopeful that this will be resolved soon!

Thanks!
