No issues at all. And like Robin in #1, upon landing in Germany, the Customs people didn't care at all...... I felt pretty upset at having had to spend a lot of time and money and effort in getting all of the documents arranged, and then in the end they just tell you "it's ok, it's ok"?? :( The airline did check at check-in, though. The documents anyway, not the microchips.
