I’m quite sure this is related to the metadata of some gateways not including the coordinates anymore. For me, for a Kickstarter The Things Gateway that started May 11th, incidentally just when some EU gateway bridge updates were executed. All still fine for a EU gateway using the UDP Semtech protocol.
