Toniebox ESP32 doesn‘t play from speakers after headphones

Hi, i hope this is posted in the right category.

After removing the headphones, the Toniebox doesn’t recognize that the headphones have been unplugged and stays silent.
Following the steps on the official website - turning the box upside down and restarting the box didn’t help.
Unplugging the AUX several times didn’t either.

Does anyone have had this or has a way to solve this issue?

Thanks everyone!
