Change Bitcoin payment processor
I really, really wanted to pay with Bitcoin, but due to your BitPay payment processor I couldn't. BitPay is unfortunately incompatible with a lot of standard Bitcoin wallets, so even if I tried with 3 different wallets, I couldn't pay (in short: they created their own "standard").
I'm sure other Bitcoin enthusiasts would appreciate different processor as well.
Here's a nice article about the downsides of BitPay, if you're interested: https://blog.samouraiwallet.com/post/169222582782/bitpay-qr-codes-are-no-longer-valid-important
As for alternative, have a look at BTCPayServer: https://btcpayserver.org (it supports Lightning network & some altcoins too)
