I am trying to use angular js material autocomplete control in my pcf control but only blank screen is showing on the browser. I had imported all necessary JS(animate, aria, material, and angular) and CSS(material-css) files.
Have you tried it in UCI as there was some outstading issue with the debug harness. Also check the content using briwser debugging in UCI to make sure that the control is configured and flowing to the right field/form.
Publish all customizations with the updated component version in the manisfest also might be the missing step.
