cant get call notifications

Yes, it also works great for me too.

So the fact it doesn't for you means that it'll be some configuration issue on your watch.

Please can you connect with the Web IDE on your PC, then on the left-hand side, paste in:

GB({"t":"call","cmd":"incoming","name":"Test","number":"01234567890"})

and then paste here what's written on the screen afterwards?

You could also enable logging in Gadgetbridge, click the incoming call button, and then paste up the part of the log from around the time that you pressed the button (make sure it doesn't contain any personal info) - but if we can track it down from what the Bangle says after manually pasting in the command, that would be easier
