I think there would be less toxic coments, if you write that your upload shedule changes and why, before you change it.
People think of comon things as there right. So we need to remind them, if its not the case.
So just ignore the people and maybe write at the End of wach chapter when the next one will arrive. If you want to make it less toxic write the date, when you can do it without stress..
Have a nice day and don't get mad at idiots, we need them to clean our asses, when where old..
