1) I tried using dynamic value - subject contains "DAM REPORT"
2) I tried using fx expression as suggested by Copilot 
     
fx contains(triggerOutputs()?['body/subject'], 'DAM REPORT')
is equal to
true
 
3) I tried using Assist me copilot button.

But none seem to work

Simple flow: Email arrival folder > Condition: Subject contain "DAM REPORT" > Condition 1: Body contain "Kok Hong" (i.e mention of me) > Post in Team Chat

    Hi there!
     
    I tested this and I believe the root cause is the condition type.  Please change to AND and retest.  As the old saying goes....works in testing!
