In the latest upgrade for a customer who was using application layers for their browser got a nice empty browser after the latest upgrade to Citrix AppLayering. Turns out that starting from version 2409 the only supported behaviour is an OS layer for that.
See the following https://support.citrix.com/s/article/CTX399422-how-to-configure-microsoft-edge-in-an-app-layering-environment?language=en_US
This is fundamental design change that you should be aware of, there is an option to put in an RFE for some other path but that shouldn’t be the preferred way imho.
Hope it helps.
