Paid for subscription still prompts for purchase. – Hidden Pictures Puzzle Play Review

My son has an iPad with his own (child) Apple ID that is tied to my family account. Subscribed to the yearly subscription (billed) but every time he opens the app it asks to choose a monthly or yearly subscription plan. Selecting “restore purchase” has no affect. Selecting yearly plan and going to the steps produces a message saying I’m subscribed through 2021.
