IBS-TH3 WIFI PLUS Will not Reset wifi

I have a IBS-TH3 WIFI PLUS sensor. I recently switched phones. Trying to add it to the new phone, and pressing the side button for a few seconds, but the wifi will not blink on the display.

How do I reset the unit or force the wifi reset in any other way?

Long pressing the button for 5-8 seconds will reset the WIFI function.
Please provide order information, and the video shows that if you press and hold the button for 5-8 seconds, the WIFI indicator light will not be displayed to email support@inkbird.com.
