I work for a large utility company and just created a rather LARGE workforce project. Being an organizational nut, I placed both my workforce and survey jobs together that were related by town neatly into their own NEW folder in AGOL.
Now, I cannot integrate any apps to my project.
From the posts I have seen relating to this problem, people have just, remade their project and everything worked fine. This would not be feasible based on how large and how long it took me to build this project.
All my survey and workforce files are shared to the same location too.
