IssueTracker

Please search through existing issues first to ensure that the bug has
not already been reported.

Please provide a short description of the issue:

When I get the active sheet in the onChange trigger, I have just the first sheet on my spreadsheet.

Please provide a small sample script that reliably reproduces the issue.
The sample should run as-is or with minimal setup, without external
dependencies.

function onChange(e) {
  Logger.log("Appel de onchange avec : "+e.changeType)
  Logger.log(SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName())  
  if ( e.changeType == "INSERT_ROW" || e.changeType == "REMOVE_ROW"){
    //MAJFormule()
  }
}

What steps will reproduce the problem?
1. Create a spreasheet with 12 or more sheets OR Copy the spreadsheet : https://docs.google.com/spreadsheets/d/1oBiU3y8fW_gfaU_AZpF_ay1BQWSqBQlEyio6zNGbQGk/edit?usp=sharing
2. Add a row or remove one on a sheet, but not the first
3. See in log (ctrl+enter) the active sheet given by the first sheet only

What is the expected output? What do you see instead?

I expect to see the correct active sheet, not the first

What is the project key (found under "File > Project properties")? The
project key does not give the Apps Script team access to your source
code or data. We use it to look up debug information about your script.
