Render queue waits for FTP upload

I Googled this issue and looked it up in this forum, and surprisingly found nothing.

When using the feature for automatically uploading an exported file to an FTP server, Adobe Media Encoder renders 1 file, uploads it, and meanwhile the rest of the render queue is paused. Obviously, the upload process takes almost no CPU or RAM, so I'd expect Media Encoder to continue rendering the rest of the queue in parallel to uploading.

Am I missing somehint obvious, or a bit less obvious (some hidden setting)?

In my company's production worklow, it's very common practice to send out a long render queue and simultaneously upload the completed files. Having to wait for each upload in order for the rendering to resume seems counter intuitive, basically making the FTP feature useless.

Thanks in advance
