Well, I work for a webcomic and we publish on different platforms:
Scarlet Society's english version is being published on Webtoon, Webcomics App and Tapas.Io while the spanish version is being posted on Webtoon and Akaya Media
Most of the time the experience is just.... meh, not much to say to be honest since it's independent work and that, we barely have feedback or active readers, most of them are on webtoon, while Webcomics and Tapas is probably one single person commenting and sometimes less than 10 liking the chapters but oh well...
And I'm publishing as well a short story webcomic on Norami.Net (Spanish), which was originally posted both in english and spanish on Tapas and Webtoon but since the owners of the website offered me contract it became an exclusive series, meaning that I had to delete it from other websites. The experience is the same as with the other series, little interactiong but welpcan't be helped.
