  It has recently been reported that hydrogen-rich materials under high
pressure trap magnetic flux, a tell-tale signature of superconductivity
[arXiv:2206.14108v1]. Here we point out that under the protocol used in these
experiments the measured results indicate that the materials don't trap
magnetic flux. Instead, the measured results are either experimental artifacts
or originate in magnetic properties of the sample or its environment unrelated
to superconductivity, Together with other experimental evidence analyzed
earlier, this clearly indicates that these materials are not superconductors.
{\bf In a second part, we discuss magnetic field screening and expulsion.}
