Since transactions with Lightning network gets completed in under a minute, this is a very good development. I just hope it won't be too complicated for people to use. I also hope a lot of people embrace this payment method because this may obviously be a trial period nd if it doesn't work out the way the company expected they might stop it.
As for fees, I don't think the network fee has been over a dollar much for a long time. I know this might not always be the case but for this year, so far, the network fees have been very low.
It may also be declined due to the merchants not getting their cut. We never know.
But, in any case, it's a great development and I hope it will stay that way.
