This question is addressed in a Nature paper on "Understanding the glacial methane cycle" (Hopcroft et al. 2017).
There conclusion is that changes in methane concentrations are driven by changes in the biosphere associated with the global temperature changes. The dominant factor is the reduction in methane emissions from wetlands in a colder climate. There ...

Just a guess, not a specialist on the topic. Pleistocene was characterised by multiple glaciations and interglacial periods. The increase in CO2 concentration and the increase in temperature normally leads to thawing of large ares of permafrost and formation of swamp areas in its place. These swamps release methane in the same way they do today.
Obviously, ...
