I meant to publish this article a whilst back over a common issue I experience when accessing LCS via VM of an environment (although this can be experienced via using a browser on any machine to access LCS) .
If opening an LCS project you notice missing icons and menu items (as shown in the images below) this is due to your browser’s security settings.
LCS Project view (missing icons and menu items):
LCS Asset Library view (missing menu items):
You can resolve this issue by adding LCS to your browser’s trusted sites (I have shown a screenshot below of the browser used on the D365 for Operations environments VM):
This will bring the menu items and icons through as expected.
Please feel free to contact me with any Dynamics 365 related questions or queries your may have!
