This issue might be caused by a corrupted browser cache, an unstable connection, or Unity Playworks is undergoing maintenance.

Possible solutions:

  • Try restarting your browser as some caches might have become corrupted, if that fails attempt a PC restart.
  • Please check that your network connection is stable.
  • If you still encounter difficulties uploading or updating creative builds then contact our technical support team.
