I haven't had the character limit problem since my chapters are broken up naturally into 3-4 parts.
Since each part belongs to a different character POV and focuses on a single scene, it tends to fall below 2k words.
For some of the short stories in Dark Bytes, I did have to break the original scene into two parts but luckily, it was easy to find that break point! I just had to do a bit more editing to make sure it flowed between parts.
(Shackles didn't have a problem either)
People like to read shorter episodes, especially on app. And I guess if the limit really bothers you, one way is to split the chapter up and then post those episodes at the same time. That way, people get the full scene anyway.
