Basic functions (calls and messages)

Got the new App - nothing changed for me.
I believe it's the Message app. The watch gets the messages from Gadgetbridge, but Messages just won't display them. Any idea how to debug that?

Debug log says:

When I send

GB({"t":"notify","id":1575479849,"src":"Hangouts","title":"A Name","body":"message contents"})

from the Emulator, the Message app just opens fine!
But then, when I want to accept or decline a message, it shows

in function called from system
Uncaught Error: Function "a" not found!
 at line 1 col 2541 in messages.app.js
a(this._l,b)
^
in function called from system

All this is super weird.

HA!
In the Emulator (Chrome) I disabled Module Minification and now it seems to be working. Still testing.
