nope doesn't happen
What is written in the text of Betty's quest?
"continued in development"
This means that her quest has not been completed yet and you have completed everything that is available at the moment.
i did everything says continued in development
The game is not finished, the content is in development.
but the update says that they are new betty scenes but I see none
Most likely, you have the free version of the game, it doesn't have these scenes yet. The paid version has them. You can get the current version through patreon or wait a bit for the free version to come out with these scenes.
