Have roblox changed developer products, Because my cash dev products don't work anymore?

I was trying my game out and the realised that when you buy the dev product you don't get given cash.

local MPS = game:GetService("MarketplaceService")
 
MPS.ProcessReceipt = function(receiptInfo)
    if receiptInfo.ProductId == 967543569 then 
        local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        player.RealMoney.Value = player.RealMoney.Value + 50
        return Enum.ProductPurchaseDecision.PurchaseGranted
       
    elseif receiptInfo.ProductId == 967961278 then
        local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        player.RealMoney.Value = player.RealMoney.Value + 200
        return Enum.ProductPurchaseDecision.PurchaseGranted
    	
	
	elseif receiptInfo.ProductId == 967558140 then 
        local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        player.RealMoney.Value = player.RealMoney.Value +600
        return Enum.ProductPurchaseDecision.PurchaseGranted
	
	
	
	elseif receiptInfo.ProductId == 967558140 then 
        local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        player.RealMoney.Value = player.RealMoney.Value + 2500
        return Enum.ProductPurchaseDecision.PurchaseGranted
	
	elseif receiptInfo.ProductId == 967558285 then 
        local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        player.RealMoney.Value = player.RealMoney.Value + 7500
        return Enum.ProductPurchaseDecision.PurchaseGranted
	
	

	elseif receiptInfo.ProductId == 967961608 then
        local player = game.Players:GetPlayerByUserId(receiptInfo.PlayerId)
        player.RealMoney.Value = player.RealMoney.Value + math.huge
        return Enum.ProductPurchaseDecision.PurchaseGranted

	end
end
