ISC-0027BW Fan does not come back on automatic after lid is reclosed, manually have to turn fan back on

It is advertised that the smart controller will turn fan off when it see’s a fast drop in temp knowing the lid has been opened, but the fan does not come back on automatic when lid is closed, even after waiting 45 mins for it to resume. I have to manually turn fan back on to resume cooking? Is this normal?

Please make sure that the ISC-027BW’s probe reading is accurate and its time setting has time remaining.
If possible, please provide the oven model and problem screenshots/data to email so that engineers can analyze the problem.
