Hello,
The remaining cooking time display requires the following two conditions to be met:
The phone must remain on the page displaying the remaining cooking time (i.e., the screenshot you provided). It cannot be exited to the INKBIRD app homepage. Otherwise, re-entering this page will reset the timer.
After opening the page displaying the remaining cooking time, the probe’s latest temperature must be more than 6°C higher than when the page was opened. If the temperature does not change, or the change is small, it will not be able to calculate.
