Hybrid mode does not support Cosmos React cases

Case view is not opening while creating the case and getting the issue
“Hybrid mode does not support Cosmos React cases”. Please help on this to resolve issue.
Pega version 8.8.3

@Raju_Yadav Hi Ravi, Do you have any solution to this issue? if yes please share it.

@SS479494 @Raju_Yadav In Pega 8.8.3, hybrid mode is designed to work with Theme Cosmos, not Cosmos React.

To resolve the issue, you can switch to using Theme Cosmos for your application. To enable hybrid mode, click on the button called ‘use React based landing pages’ in your application rule and save it. After that, open your portal channel and you should see the new ‘landing page’ option.

This will allow you to use the Constellation UI tables and other features in your application.
