It looks like Lightning Network is active, but the quantity of people using it is increasing slowly. In fact, fees have gone down lately.
I share your opinion here. I have observed that fees have gone down lately which I thought was weird, but now it starts to make sense. It does seem like the lightning network is indeed active, but it seems like a beta version currently since they tell us to be careful and be aware of the risks involved. Personally, I am happy that it is active and people have begun to test it and I am expecting all users to enjoy the lightning network benefits within a few months.
