Changing previous episodes, HELP

Hi sweetie pies!
I have published 8 episodes of my story and I found some things I’d like to change.
If I change all the previous episodes does the readers have to read the story from the start or can they continue where they left off?

I just want to add my moving intro into all the old episodes and write a note in the first Episode … i want to change all Of them… :s

I’m in the same situation. :frowning: So did you figure out if the readers have to re-read the episodes?

Didn’t figure it out… did you?

Not really…
