1. Definitely understand the sentiment, and many on the team are heavy users and advocates of p2p exchanges instead. This is just the first step as it's the lowest lift, with direct p2p exchange integration on the roadmap!
Good to hear, and having more options is always good.
To give you some ideas, is Robosats for p2p LN to fiat trading and they have a list of compatible wallets, you can consider adding support for Envoy in future:
https://learn.robosats.com/docs/wallets/PeachBitcoin is also doing a great job with their app, so maybe you can do something similar or make some cooperation with them.

Once we have Lightning support in Envoy we will absolutely ensure that we are compatible with Robosats, and perhaps even explore a direct integration.
PeachBitcoin is also doing a great job
We agree

Unfortunately they don't allow US users, which is by far the largest customer segment for us. Would certainly be interesting to explore some sort of integration in the future, however.
