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 the new version of the app, 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 and download the latest version. The latest version should be 6.2.
If you can't download version 6.2 or are having other issues with the app, then email us at firstname.lastname@example.org, we'll be happy to help you!
