I have followed the instructions in the quick start for training a custom model . Docker Desktop is running, SAS URL has been verified, Form Recognizer end point and key have been verified, file location has been verified. In addition the firewall has been opened my access has been set to Storage Blob Data Owner. I have created numerous projects and connections with pdf and png documents in Azure blob containers, including the training forms provided by Quick Start. The forms do not appear in the label editor for any of these projects. What am I missing?
