Lightning Merchants:

Cash App seems to have quietly dropped support for Lightning payments initiated from a third party website.

If your web app uses a "Pay in Wallet" button, that button will send your customer to a confusing error page in Cash App, if your customer attempts to pay.

Easy solution: either provide this link for your customer, or copy the content of this page onto your own website: https://rizful.com/pay_lightning_invoice/cashapp
