I have recently set up subscription flow on app. I have configure the subscription with Pricing and an introductory offer of free trial. Submitted the version of app and got it approved. Now I'm trying to release the next phase with loaded features... But this time when I try to test the same via testflight, the free trial introductory offer(which is still active) isn't showing up against the subscription plan. Same happens in Sandbox environment as well. Need some help to get that free trial option to show up on the subscription pop-up screen.
