I thought it was best to address everyone here in one post, as you are all seeing the same error. This error means that the currency you are currently selling in is not supported by PayPal at the moment. While PayPal is available in over 200 countries, they support 25 currencies. These are the currencies PayPal supports:
I'm afraid AED, ZAR and BWP are currently not on this list. Moving forward, you can switch your currency to one PayPal does accept, or you can take a look at another option for a payment gateway; whichever you feel suits your business best! There is also the option of switching your currency, then using a currency converter app so your customers could still see your site in your regional currency; only the checkout would be in another currency.
If you wanted to change your currency, this is something you can go ahead with! You can go to the admin and select Settings > General, then scroll down to the currency section to switch.
However, the option to switch your currency would be locked in the admin if you have already made sales. The reason for this is so you can reach out to our support team and chat with us about the effects this will have on your business if you were to change currencies after sales have been made:
With Shopify actively encouraging merchants in some instances to adjust currency for new features, we want to make sure merchants are properly aware of any potential areas they need to be aware of for their account.
That being said, there are also some possible workarounds!
Let me know if any of you decide to switch your currency after a sal has been made, I can help you make the switch.
