After receiving the demo version of the game / program, the button for receiving a gift (Redeem Gift) disappears.
After the expiration of the free trial period, and regardless of the period, even if you delete the installed version, you cannot receive a gift to your account.
If at this time you search for a game in the store through the search, the game is considered purchased. On the game page, an offer to purchase will be shown, i.e. there is no access. I attach a screenshot.
My request is to pass this problem to the developers - it needs a solution.
