I have installed the 2.2.0 SDK in Unity and everything works ok except I always get an error that makes it unusable: "Invalid Key or package name". (the same happens with any other 2.x version).
The error arises ALWAYS 4 minutes after the app starts and until then it works perfectly well: initializes and detects the image patterns correctly.
I am quite sure I am using the same app name and package name both in Unity and EasyAr SDK authorization web. It looks like an error in the SDK, since I have tested it many times very carefully, changing package name, generating new keys, etc.
Please, solve this error, otherwise EasyAR is a buggy useless SDK. Thanks
