The action happens randomly, but daily , when commenting. Its either a “something went wrong” or “not found” errors that pop up when trying to post a comment. If you tap the post again, it then duplicates the post because while it looks like it didn't post the first time, it actually did. I don’t know how much more specific i can get than this.
Watch list is slow. It loads slow, it updates slow. I usually just end up searching the drama and updating my episodes watched from the drama page because it takes forever for the edit to work in the watch list page.
I type faster than the letters show up on the comments. This is how slow the site is. I don’t know any other way to be more specific than i already have in my original post.
