IBT-4XS not being found in InkBird App

I recently got a new iPhone and tried to connect my IBT-4xs to the new app but the app does not find the device.

Hello,
Please understand that the app supported by IBT-4XS is ‘BBQ GO’ app, it is not the ‘INKBIRD’ app.
Please use the ‘BBQ GO’ app.
When connecting, please turn on the Bluetooth and location permissions of the phone, and make sure that the permissions of app in the phone settings are all agreed.

Is IBT-4XS B still not compatible with INKBIRD app? The BBQ app is a total disappointment, especially when coming from the INKBIRD app, which I use with other products. Could you at least improve the BBQ app to match the wood the INKBIRD up, or even better, upgrade the Inkbird app to be able to connect to IBT-4XS B?
