Actually OR condition should work with IN operator. Also the workaround given in the link provided is tedious and will not work in our scenario. We have to monitored only specific number of email Id around 8-10. So we want a condition like
Email :To Recipient contains [Test1.email@example.com] OR Email :To Recipient contains [Test2.firstname.lastname@example.org] etc.
I think we can achieve this using IN operator, but it seems to be not working. Could you please confirm is this a product bug?
Workaround for us is to add the multiple else if condition and repeat the steps in each else if.
