Flux Pinning is separate from the Meissner effect. Flux pinning only happens in Type II superconductors, where the Meissner effect of expelling external magnetic fields happens with both Type I and Type II superconductors.

Meissner and flux pinning have to be mutually-exclusive, so so do we know the transition condition in LK99?

NB: This may be painfully obvious from the figures.
