I as Admin am still able to run the Conga button solution, but my user gets the "Authorizing" page in Conga and it never moves on from there. I installed the Conga Auth as connected app as permission but still the same issue. Anyone else run into this?
Thank you, Divya, for the very detailed answer. I'll try these steps. Hopefully we will be getting rid of Conga this year, it is such a headache.
