Fellow birder from Russia Alexander Yakovlev birdchuvashia has asked me to help out with the following.
They manage Birds of Russia project and the map that’s currently used is a bit off and does not include maritime borders. He’s created corrected .kml map, it’s size is less than 1MB, but he’s still cannot upload it - error message says the file is too big.
What steps should he take next? What additional info should İ ask him to provide?
