Upload failed
We've had tens of thousands of successful uploads from around the world so we know it works virtually every time.
Nevertheless, some people have reported infrequently that their friends tried to upload, but the upload failed.
In almost every case, the issue was either related to limited bandwidth or their phone (or computer) — something like ad-blocking software interfering with our app, even though we don't have ads.
Please have them try recording/uploading on a different browser, or on a different device.
If they are still having issues, please let us know.
