Some errors only affect one customer or customers with a device from a specific brand. These issues are more complicated to investigate as they can be device specific.
In those cases we recommend that the customer also checks if the Google Play Services are up to date on her device.
This can be done by following this link on the device. The Google Play Services app supports the correct playback of video material.
