What’s the deal with AQUA Wallet and why does anyone like it?

I’ve personally seen two people in the past month attempt to pay a Lightning invoice with it and it failed both times. The worst part was it said the payment had completed on the sender’s side but the recipient never got paid. After the invoice expires, the sender eventually gets notified and the sats are returned to their wallet, but it can take 24 hours. Meanwhile, the merchant either loses a sale or the customer has to pay using another method while waiting for their automatic refund.

This is a frustrating experience both for retail customers and merchants, and it’s things like this that are going to kill Lightning adoption.
