This update broke the app

The Stop Cooker doesnt work. The Start Cooker doesnt work.

If you stop it manually and then set the temperature and time in the app the Start Cooker doesnt work.

If you set the temp on the device and then start it, the time set in the app shows as _zero_

How can I recover the previous version that worked?
