Why isn't Storyblocks working via cellular connection?
At this time, connections to Storyblocks through certain cellular providers (including AT&T) may fail due to a configuration issue. We are continuing to investigate this, and hope that it will be resolve this issue in the future.
In the meantime, in order to use your Storyblocks subscription, you will need to access it via WiFi. Once connected, select the Storyblocks clips you will want to use, then select the Import Media button (upper right corner of Library window), and select Add to Cached Media. Your media will be accessible off-line from the Cached Media folder at the bottom of the Storyblocks library.
