there is definitely a bug from there part.
As of this post, to get a transaction into the next block you would most likely need to send with a fee of
950 satoshi/byte. Therefore, a high-priority small-size (226 byte) legacy transaction (which makes up a very large number of recent transactions), would cost somewhere around $12-14.
any time frame?
It's hard to put a time frame on it. The last thing you want is a rushed LN wallet release which could end up having serious bugs.
It may also take a long time until the majority of
services begin to accept LN transactions after an LN wallet is created.
