When a user clicks on a link to a form they do not have access to which is normally sent to them through an email link sent by a workflow, the linked page will be stuck showing the loading page attached.
This loading page confuses some users as they believe it is something wrong with the site and not that they don't have the correct permissions for the form.
Thank you very much for posting your feedback for our review. At this time, we will not be adding this request to the near-term backlog, as we are focused on other highly requested features. However, we reevaluate requests every quarter and will reach out if priorities change. Please keep the feedback coming as it is critical for our longer-term planning.
