PayPal Dynamic Currency Conversion simply lets PayPal to complete your transactions using your card's currency. This simply means if you link a Naira debit card (Mastercard or Visa) to your PayPal account and use the PayPal account to purchase from a seller whose products are listed in US dollars, PayPal conversion rate will be used to bill your Naira card instead of the MasterCard and Visa currency conversion rate.
Unfortunately, there are cards issued by some banks which do not support this conversion process. If you've linked such cards to your PayPal account and you try using the PayPal account to pay online, the payment will likely fail.
So, if you get "Your payment method isn't working. Do you want to try again with another card or bank?" error when trying to make payment online, this is likely the reason why you are getting that error. GTBank MasterCard is one of those Nigerian cards that do not support DCC.
So, what's the way out?
