This doesn't answer your question, sorry, but I also question if I'm missing something with Azteco!

I've been following them for a few years now but only attempted to test their service a couple of months ago with the proverbial small amount of cash.

It was a delightful experience. To redeem the voucher couldn't have been any easier. I was sort of hooked on the idea. Fees were admittedly high, but I expected that going in anyway.

However, when I tried to repeat the exercise a few weeks later with a slightly bigger amount (mostly because Phoenix ate up most of that first small amount to open a new lightning channel) it failed to redeem.

So I've also been hunting for possible explanations of what could have changed. While it may not mean anything, in the process I learned that they apparently (recently?) got a $6m grant from Jack Dorsey and I'm wondering if that could have changed their business model / priorities?

If anyone knows, please let us know...
