Several members of our community were unable to download content like PRO sounds or guided meditations because of this error message. This was due to a recent change in the way Android handled SSL certificates. Our team went ahead and fixed this issue in 6.2.
What to do?
Simply check which version of the app you installed. If it's 6.1.2 or below, then simply go to the Google Play Store update the app.
If you can't update the app or are having other issues with the app, then email us at firstname.lastname@example.org, we'll be happy to help you!
