I didn't think this was controversial.

The pole shifts gradually a few inches, maybe a few feet per year.

Some theories claim, based upon analyzing rock patterns and what direction crystals formed inside rocks, that there were major pole shifts in the earth's history.

What happened, in February 2019, was that the north magnetic pole was moving so quickly that a new version of the World Magnetic Model had to be released ahead of schedule. Normally the model is updated every five years, with the next regularly scheduled release in December 2019.

This did not require any changes to the GPS satellites, but it might have resulted in a software or firmware update to the navigation systems that use the signals from those satellites. These devices use the World Magnetic Model to correct for the magnetic declination—the difference between magnetic north and true north. For example, on my iPhone, the Maps app shows my location as a blue dot with a little arrow to indicate which direction I’m facing. The phone uses its internal magnetic compass plus the World Magnetic Model to draw that arrow in the right direction.

The changes to the WMM probably didn’t make much difference for the casual iPhone user like me, but for precision navigation north of 55°N, the old model was no longer sufficiently accurate, so it had to be updated a bit early.
