This error occurs with a few of our apps and is related with Google and Android 6.0. Google is already trying to fix it (see also Issue 9071).
We expect Google to solve the problem with the next update. Please use the Outdooractive app by then, because it should work properly. In case you#re already using the Outdooractive app, please make sure you’ve installed the latest update. If so, plase contact us here.
