The admin override password has changed in the new Apollo firmware. If you are using this as your password then it will no longer work. I would urge you to set up your own password so it will not be affected by this in future. We can give out the new admin override password to the registered owner of the tester if you email a request to email@example.com.
Thanks and kind regards
