Anything else?

Perhaps this is still related to #531.

Have you been able to upload a single file <5 gb yet?

Have you been able to upload a single file <5 gb yet?

Yes, I managed to upload and retrieve multiple files ranging in size from several hundred MB to 4 GB before I raised this issue.

I haven't tested the latest version though.

[justin59805]

I'm having issues like this on the latest version (v1.12.2).
