Hi I can able to control DataCards by audience/user on visible parameter its means when the user is not part of these syntax,
If(OR(User().Email="test.user@contosso.com", User().Email="test.user1@contosso.com" ),true,(IF(OR(User().Email="test.user2@contosso.com", User().Email="test.user3@contosso.com"), true,IF(User().Email="test.user4@contosso.com", true,false))))
then the user will not able to see this DataCard. And it works fine. now the problem is how to control the DataCards lock and unlock or the DisplayMode.disable by audience/user. Thanks!
Regards,
Ian
