IHT2PB Will not connect

Hi My IHT2PB will not connect to my phone, I have followed the manual instructions and still cannot connect, i have even reinstalled the app but still no luck any help would be appreciated

Please use the latest version of INKBIRD APP.
When connecting, please put the thermometer next to the phone. Please turn on the phone’s Bluetooth and location functions. Please make sure that the Bluetooth of the mobile phone is not connected to other Bluetooth devices.
Please follow the instructions in the manual and the app.
If it is possible, please test with a different phone in order to rule out that it is caused by the phone settings.
If it still has problems, please feel free to email at support@inkbird.com
