Problem with tracks recorded during sessions

[SteveW]

Sometimes the recordings of our sessions work very well indeed. Other times, though, there are tracks that repeatedly fail to upload to the server. Looking at the logs in the file manager, the errors are shown as "Network-error" or "AWS-upload-failed". Sometimes, after repeated attempts by the file manager, the tracks do eventually upload: other times they never seem to get uploaded.

Does anyone know why these errors occur and whether there is anything the user can do to mitigate the problem, please? Anyone else experienced this?

Thanks

Steve
