I cannot receive calls on my Apple Cellular watch unless I remove the Bluetooth link between my iPhone and my hearing aid!

I have a new Apple watch 11 cellular plan (Telstra) and can use it to make calls but it fails when I try to receive calls. The odd thing is that the problem disappears when I remove the Bluetooth connection between the iPhone and my hearing aid. Then I can receive incoming calls okay. This is interesting but useless. If I get the call when I am in my bed room and need to go to another room to switch off that Bluetooth connection, that is some kind of sick joke! So if all the extra money I spent on the Cellular model was wasted it is a bit late to find out.

Unless someone out there has a solution for this problem!
