Hello, some of the layers on our public map randomly disappear when the application is opened. For example, here are two screenshots of the same map showing two different set of contents. 

Screenshot 2026-07-20 165139.jpg                     Screenshot 2026-07-20 163517.jpg

We are running Experience Builder on Enterprise 11.5. Any ideas on why this is happening?

Thanks for your help!

Hello @dsinha, while not being able to dig in too deep, I am getting many browser console errors when I try to load the app which is probably why some show and some don't. It also might explain if you can seem them on your internal network vs a public device. It might be a firewall setting on your network or a sharing setting in Portal.

Thanks for the observation @Brian_McLeer. Actually, both screenshots were taken on the internal network. I am very worried what public viewers on external network are able to see (if new to the app, they may not even know that some layers are missing!!). 

I wish I knew what is causing it.

You're welcome @dsinha. If you have an IT Network/Support team I would probably ask them to check firewall settings/port settings/etc. (well beyond my skillset).

Thanks again @Brian_McLeer. Submitted a ticket to Esri Tech Support to see if they can help identify the cause. Will report back if there is a resolution.
