Louis Tomlinson - Miss You Lyrics Meaning

I always had the feeling like "Miss You" is about Harry, wether as a couple or just (Best) friends in general.
Especially because of the lines "Now I'm asking my friends how to say I'm sorry, they say 'Lad, give it time, there's no need to worry.'", like he messed up big time with Harry and never found the words to apologise.

I read an article where Louis stated it really is about Eleanor and I can see that too, but on the other hand I don't see the reference in a few lines.
E.g. "But we can't even be on the phone now, and I can't even be with you alone now. Oh, how shit changes, we were in love, now we're strangers."
Louis and Eleanor got back together in 2017 which is also the year when the song was published.
I'm pretty sure that IF Louis and Eleanor had really alienated that much, then it would have been by far more difficult for them to come together once more.
Personally I believe it's about Harry, like I already said above, Louis messed up and he wants to rekindle their special bond but Louis doesn't quite know How.

So to put it in a nutshell, I think it could be about Harry or Eleanor :)
