IBT-26S 5G only works in bluetooth range

IBT-26S 5G shows connections, bluetooth and wifi, but drops connections when out of bluetooth range. App shows IBT-26S 5G offline when out of bluetooth range, but within same wifi.

Hello,
If you put the IBT-26S next to the router, and the phone turns off the Bluetooth for testing, will the IBT-26S WIFI connection also be disconnected?
If yes, could you please email support@inkbird.com with order information, phone model, and a video of this problem?
