V15 messed up my banglejs ?

ok, this is odd. I got back to 2v15 a few hours ago. I checked barometer about three times. Still zero.
Just checked again for fun before trying above procedure, now:

Bangle.getPressure().then(d=>{
: console.log(d);
: // {temperature, pressure, altitude}
:});
=Promise: { }
{ "temperature": 26.82648722330, "pressure": 1018.17897384550, "altitude": -40.95649506835 }

I then did a long-button-press reboot, now reads zero again.
