Hi,
In the AEM React SPA application when the author environment page loads the user is not able to see any of the components in the content tree and not able to configure the components. However when user clicks on Preview option and then on Edit then content tree loads up correctly and the components dragged on the page could be selected. This issue is on all the environments LOCAL, DEV, UAT and PROD.
Thank you for your time, consideration, and experience!
Regards,
Varinderjit
