I know that this forum is not the correct place for this question. But I asked on Samsung developer forum and could not get any response.

Maybe someone here can help me.

I am trying to create a watchface with trial period on Galaxy Watch Designer.
I add the setting from “in app purchase” menu.
Selecting a time to expire (eg. 3 days) and item number as 1.

Then when publishing the app , I go to in-app-purchase and add an item with number “1” and title “unlimited version”

I think that must be it. Anything else required ?

When I submit the app for approval, it gets rejected and the reason is “can not be purchased”
Also, the approval team sends me a video file showing that it really can not be purchased.

what am I missing ?

thanks.
