When publishing branch versioned data for the first time changing from traditional versioning, allow for required fields to be turned on by the right-click option in the 'Share As Web Layer' pane. I received 465 errors which I have to go into each layer and turn on all fields that are required to be turned on to publish branch versioned data to Portal. Being able to select the errors, right-click and choose 'turn on field' would be a great improvement.
