going to be honest it just astounds me how many basic website features webtoons lacks sometimes. Like it's essentially an art site but didn't add png support until this year. And you can't even click on links in creators notes and such.
I think webtoons just doesn't have real competition (I know tapas technically is but it isn't nearly as big as webtoons) so they can just ignore problems with their site.
I think if tapas had the same amount of readers webtoons has a lot of creators may not even bother with webtoons because of it's lack of creator options
edit, this isn't to say tapas is without flaws because this site also has some issues (hard to tell what's premium or not, both sites have issues with smaller creators having difficulties getting their work seen without a front page feature, ect) but webtoons is the bigger site with more money so it's just weird to me they can't fix simple issues I guess
