I have enterprise portal at 11.3. We published features in a map from pro set to share with the organization. We need to share the features to another software so when we brought it into AGOL we choose to save the credentials option. We go to open the map in AGOL though it acts like it will open but usually warns it can’t open several of the features and some may partially open but can be seen or popups don’t work and it crashes giving a warning. In reading the logs no real clear issue though timing out is part of the issue. We tried limiting number of features still occurs.
any help appreciated
