According to document, there should be an option "Site from template" when Click create button. But these is no this option in my author environment.
Are you using Adobe Experience Manager as a Cloud Service environment ?. Please check as I believe that is the reason for you not able to see Quick Site Creation feature.
I'm using Adobe Experience Manager as a Cloud Service environment, not use the local development environment.
Please check if you have latest Cloud SDK. I tested using SDK Version "AEM SDK v2021.11.6023.20211111T113531Z-211000" published on 2021-11-19 and I am able to see Quick site creation feature.
Experience Manager as a Cloud Service follows a monthly release cadence. As a result, new features are available as continuous updates to Experience Manager every month.
@Bhuwan_BThanks for your input, you can see I'm using the AEM SDK v2021.11.6023.20211111T113531Z-211000. But I really can't see the Quick site creation feature. Is there any other configuration/settings needs to do?
