Comments.Text: @petednz-fuzion Great suggestion as usual, but unfortunately no dice.  There are no errors thrown, not in the console, nor logs.  I triple checked all tokens, the subject, etc.  This happens even on a blank, new email.

Comments.Text: @petednz-fuzion Nope, it's pretty much only the popup window when using mosaico.

Comments.Text: I'm having a related issue on both Mosacio and traditional mailing, where I get the same error warning listed above. If I create an empty file, it goes away but I'm still getting angular errors in the console debugger, e.g. Possibly unhandled rejection: {"error_code":0,"entity":"Mailing","action":"create","is_error":1,"error_message":"Mailing has not been saved, Content maybe out of date, please refresh the page and try again"} when I try to send the email. Drupal 9.4.0, CiviCRM 5.50.3.

Title: CiviCRM - Mosaico - Test window opens but buttons are not clickable?
ThreadText: # CiviCRM - Mosaico - Test window opens but buttons are not clickable?
  
  (Asked by: username_0 on 2022-04-07)
  
  Drupal - 9.3.9  
  CiviCRM - 5.47.4  
  Mosaico - 2.8 -> Attempted upgrade but ran into the issue being tracked on github, so downgraded back to 2.8.
  
  When composing a CiviCRM mailing using Mosaico, no matter if it is a new mailing / editing an old one, the test buttons are all visible yet not clickable. This issue started after moving from Drupal 7 -> Drupal 9. The only "error" (warning) thrown is:
  
  ```
      page not found /libraries/civicrm/core/bower_components/angular/angular.min.js.map
  
  ```
  
  This is, as far as I could tell, only a dev console related error, not an issue that would cause the issue of not being able to click the buttons.
  
  I have been unable to find any related issues on the respective issue trackers, nor on SE / Google.
