Known issues

These are limitations that work exactly the way they were built, not faults. If you hit one, there is nothing to fix on your side — but knowing about it saves you an hour of hunting. If what you are seeing is not on this list, it is more likely a setup problem than a limitation. Start with the pages at the bottom of this page.

Mercado Pago

A payment link can be paid more than once

A Mercado Pago checkout link stays usable after it is paid. If someone pays against the same link a second time, DMLY reconciles that payment onto the same payment record rather than creating a new one — the second payment does not show up separately.Send a fresh link for each amount you want to collect, rather than resending an old one.

A partial refund still shows as paid

Mercado Pago does not change a payment’s status when only part of it is refunded, so the payment keeps showing as succeeded in DMLY. Check the refund in your Mercado Pago account for the true amount.

You cannot charge a saved card

Mercado Pago runs through Checkout Pro, which always sends the customer to a checkout page. Charging a card you already have on file is not supported for this gateway — every payment needs a link the contact opens themselves.

​

Currencies you can use for payment links

Payment links support a fixed set of currencies: USD, EUR, GBP, CAD, AUD, NGN, GHS, ZAR, KES, INR, AED, SAR, QAR, EGP, BRL, MXN, SGD, HKD, ARS, COP, PEN and UYU. Anything outside this list — including Chilean peso, Japanese yen, Kuwaiti dinar, Bahraini dinar and Omani rial, which don’t use two decimal places — cannot be used for a payment link. If your currency isn’t on the list, take payment outside DMLY and record it manually. See Payments and gateways.

AI providers don’t all do the same things

Which AI provider you connect changes what your AI replies can do. A knowledge base (documents your AI can search when it replies) works only with OpenAI or Google Gemini. If you connect Claude or DeepSeek, there is no knowledge base to set up — the option is not available for those providers. See Knowledge base and AI replies.

Something else is wrong

Most problems are configuration, not limitations. Try these first.
