Haven't tried Blitz wallet yet. Does it support lightning address? BOLT-12? Since liquidity is handled behind the scenes, how does it handle the situation when there isn't enough inbound liquidity to receive a transaction? Does the transaction just fail, or is a message displayed to the user, who may or may not have any ifea what liquidity even is, that they don't have enough inbound liquidity to process the transaction? Or does an LSP provide additional liquidity on the fly, and the user is assessed a higher transaction fee than they expected?
