Polar shift and solar minimum are two entirely different subject with no relation to each other. A magnetic pole shift only affects which way your compass points and leaves traces of magnetism in newly formed rocks.
The Earth's magnetic field is subject to the Sun's, though. And the other planets (milankovitch cycles). It's pretty likely that a pole shift isn't just an independent thing that the Earth does in a vacuum. Polar shift is very likely affected by the magnetic fields the Earth is bathed in, like the Sun.
But it has never affected life in the past.
Look up solar minimums. It does affect life, it massively shifts migration patterns, farming zones, fishing, etc

That may be so, but we still won't notice a thing unless we're using compasses to find our way through the woods.
