I had the same problem and was ‘fobbed off’ with the latency excuse. I didn’t believe it, especially as it had happened after I’d tried changing the auto save amount. I then got another rey saying I was correct and it wasn’t the latency issue, it was due to the fact that changing the amount meant it becomes a manual save and only allowed 10k manual so it had failed. Yet I now have another auto save, I change it again and it goes through without a problem leaving the previous one pending. So many times given lame excuses for problems rather than issues being dealt with.
