Not able to add landing pages in APP studio

I am not able to add the landing pages in the APP studio.

Portal → Landing pages - The system is showing the dialog box which says login is required.

Application is setup properly with traditional UI. I have tried with the preview application->Design mode, but could not find the UI pages option in app studio.

Are you using any SSO login?

@SohamM95No, I am using cloud instance provided as part of lead system architect mission v8.8

@shanp1

Yes it is an SSO login. It automatically logs in from your Pega Community login. Try to login from a new bowser session and from there open the instance from My Trials.

Can you please check with the incognito browser?
