If a user is simultaneously signed into AGOL and accessing a Portal Survey (created from S123 connect from existing federated service hosted on ArcGIS Server> published> accessed via hyperlink) there is a Token Error and the survey breaks Case # 02105855. The case resulted in a bug but was claimed as 'an irrelevant workflow' and was closed 'not in product plan'.
This will continue to directly affect any organizations that need to make a survey from an existing portal feature class and who want to access it from the web.
Please fix this issue!
