Omnibus F4 Pro V3 barometer

I’m getting somewhat varying readings from the barometer on my Omnibus.

It’s been OK for some while after I bought it, but now when I’m flying it tends to show sudden height changes - particularly when I bank the quad! The height being reported changes from say 20 feet to 60 or 100 - with no significant actual height change!

I’m using INav, and have the FC in a plastic case, with the barometer covered in light foam (all the same as I’ve had since it’s original installation).

I’ve just updated to a newer INav version to see if that makes a difference.

Anyone else seen such a problem?
