What the payment messages mean

If you see "We couldn't confirm your payment", check your GlueArrow wallet. If the money left it, press Upgrade to Pro again. You won't be charged twice in the same month. If you see "Your payment was not accepted", you have not been charged. Try again in a few minutes. If you see "We couldn't reach the payment service", you have not been charged. Try again in a few minutes. If you see "We can't take payment right now", you have not been charged. Try again later today. If you see "Not enough in your wallet", tap Top up wallet, add money, then come back and press Upgrade to Pro again.
