  1. If you have faced the reported issue on any specific component, then share the component list to us

  2. Whether you upgrade your application Syncfusion version with or without angular version?

Hi Nagendra,

Initially, this issue has occurred in the following version starting from (v20.3.38) which was caused by setTimeout function that slows down the rendering of Syncfusion components. This is a known issue at our end. We have added this delay to resolve the issue of child templates not being rendered in karma unit tests. And we have fixed this issue in our latest patch release version (i.e. v20.4.40). So, to resolve this issue please update our Syncfusion components to the latest version.

Please refer the below release notes:

Please get back to us if you have any concerns
