Hi,
I found a strange error.
If you place an icon (whichever external library, not sure about uploaded svg) inside a Nav Item Block (which sits inside a Nav Nestable), an icon is not being rendered. If you place a div or block inside a nav item block, and then an icon inside a div or block, then it’s fine. Also, if you place an icon directly inside a nav nestable, but outside of nav item block, then it’s fine.
To see the issues, no refresh is necessary. You can just take an icon out of div and it’s no longer being rendered
