Behind the scenes

1. Play button on videos in the Chrome browser: Resolved an issue that caused a loading indicator to display instead of the Play button for videos viewed in Chrome. The Play button now displays as expected.
   
2. Removing web conferences from calendar events: Fixed an issue that caused an error when the web conference option for a calendar event was changed to None. The web conference is now canceled as expected when the web conferencing tool is removed from the event.
   
1. Note: When removing a web conferencing tool from a calendar event, you must also remove the Join Meeting link from the Description tab.
