There is no update from the plugin developers. The plugin is NinjaForm and possibily Agile Store locator which both use Agular.
The theme does not have any Angular. It’s a custom them developed by us. Only two plugins contain angular, which are up to date but the issue is still showing.
The theme is custom developed, and there are no other third part themes on the system. Also all the plugins are up to date as of now.
