Current behavior

Tried to fallback to primeng 5.2.7 but issue is still there

Icons should still be visible. This issue was not present on previous angular versions.

Did you install primeicons and include the css?
Thanks, should have looked at the blog post mentioning primeicons replacing font-awesome.
After installing it and added "node_modules/primeicons/primeicons.css" in angular.json then icons are displayed now.
