Hello Randy,
We hear your pain, and we have a plan for that, but we may need your help.
My name is Blake Bilbo, and I'm the Head of Support for GEO Jobe GIS Consulting. We're the creators of the top THREE apps in the ArcGIS Online Marketplace, which includes Admin Tools for ArcGIS. We're developing a NEW product which will scan your organization for issues such as this, and provide a quick and easy call to action to fix these issues in bulk. We're calling it "Clean My Organization."
I am reaching out because this is precisely the kind of "Broken Web Map" (among many other common issues) that we would be aiming to fix with Clean My Organization. We would really like to get in touch with you to test this upcoming product to ensure broken web maps and layers will be effectively recognized during the scan and a solution is quickly provided in the app.
Please contact me at bbilbo@geo-jobe.com if you are interested and can help us out. We would really appreciate this opportunity to release a product many folks can take advantage of, and we believe the key to this will be real-world sampling of various content that we can analyze and address.
Thank you for your interest, we hope to hear from you!
