It means there was an issue when trying to upload the video to the cloud. However, what I have found that sometimes even clips that show that, you can still play it by tapping on the middle icon. Other times it will indicate that the clip in unavailable.

If you get consistant thumbnails of those there may be a issue with the wireless signal or the camera staying connected.

*I edited the previous post to clariy that the clip is not always available and that if the clip actually failed to load it is not available.

Thank you!

I've only had this camera for a week and I'd never seen that before. 

Have a great day!!

I have the same problem. Thanks.
