Can't buy watch face using coupon codes

[miafschr]

I recently found out that you can download watch faces using coupon codes, therefore getting the watch face for free. But now when I go to the billing menu, the option to buy is greyed out and I can't purchase the Watch face? I am using the Samsung Galaxy Active 2 with a oneplus 7 phone. I have used coupons to purchase watch faces in the past and it has worked perfectly but for some reason now the option to buy the Watch face is no longer working. What can I do to fix this problem?Buying a watch face using a coupon code, the option to buy is greyed out

I have the same problem.

It's solved now

Just add a valid credit card and the buy option will be activated 😎

Use the coupon normally and it will apply

Before I could use the coupon without registering credit card. I can't see a reason to register my card to "buy" something that cost nothing

Same Problem any issue please

Yep, I think that Samsung changed their policies.

Yeah, it's pretty stupid. I added a credit card and was able to download the watch face but I was charged a 50 cent processing fee, which is ridiculous.
