I redeemed the code on my ipad. If I recall correctly, when I first entered the code on the ipad, there wasn't any kind of acknowledgment. I tried to reenter the same code and got the message that it was already in use. That's when I checked the VP and saw that the app had the icon to indicate it was freely downloadable and it downloaded without any problems.I tried adding coupon code on my ipad like any other code or gift card but it was not recognized. On vision pro, I am not seeing option to enter code. When I click buy the app it is directly asking me to confirm the purchase but no option to enter code.
