Sudden Elevation in Checkouts using Paypal

Normally 10-15% of my customers check out using paypal, the rest use credit card via Shopify processing. Over the last 2-3 days, that number jumped to 40%. I can’t find any indication of issues with credit card processing at checkout.

Is anyone else noticing the same? Any theories?

Why would something that happened clear back in October create a 200% difference for two days in January? It didn’t happen progressively, as I said it was sudden. This looks like a ChatGPT response.
