SPERRY on Nostr: I was able to pay tiny amounts on nostr using CashApp when I don't have another ...

I was able to pay tiny amounts on nostr using CashApp when I don't have another wallet connected, I choose CashApp after it creates the invoice and it auto opens the app and works perfectly. If I create an invoice for 13 SATs in another wallet and try to paste that into the app itself, it vibrates and says 5000 SATs min.

Not sure how they're different, but one works, one doesn't. I felt like a few weeks ago I was able to paste the invoice for small amounts and it worked perfectly, was I imagining this?

Thanks so much for the reply.
