Just general info I know of:
The Early Access on a chapter expires after a week, but the time is also accumulative if they add another EA chapter before the week is up.
There’s another feature being tested known as “skip-the-wait” which is an 11-hour wait time that only starts counting down when the reader has seen it regardless of when the chapter was published.
I’m just guessing that it might be a different addition to the skip-the-wait since many ppl complain about the 11-hour wait time (myself included) or a new test of Early Access? I personally haven’t seen a wait time of only 5 hours straight off the bat, unless I’ve literally only got 5 hours to go from the week countdown.
