I've just revisted Vuforia 4.0 and find that regardless of network connectivity I get the aweful no network error message and see this is the same as this closed thread:
But whereas that thread refers to the editor I am getting this on an iPad which is online
Thanks
after numerous reinstall I get no network message on start when there is network and then subsequent runs say invalid API key even though it is valid?
this thread applies but does not fix this issue?
