A product advertised as having a 1 year warranty and then the seller not honoring the warranty is the product not being sold as described.
But yes, it's my mistake for assuming the purchase protection would... protect my purchase.
And now I won't make that mistake again. The value isn't there, neither with their aggregation service nor their credit product.
I can just use Google Pay with a credit card, both of which are more convenient and offer better protection than PayPal does respectively.
