Configuring Multiple Audience in Experience

Hello Target Users,
I have a scenario where i have to show different experiences for mobile and non-mobile users within the same activity. So i am using multiple audience in configure option to solve that (screenshot attached).

But this seems to working only for non-mobile users, mobile users also seeing the same experience as non-mobile users. Am I missing something? or is there any other way to create activity for this scenario?

Thanks in advance!
