Sorry for the confusion, the new Lolin V2 shields that we are now selling do indeed need a new version of the library but I can confirm that the updated library available via Lolins website does work with the shields we currently have on sale.
I've now updated the first post to include this new library and the test sketch that I've tested with one of the shields taken out of our current stock. Can you confirm if the example sketch and library in the first post works for you or not. Remember to remove any old libraries from your libraries folder before giving it a try.
