Export JSON to share collection broken on Linux?

How can I share collections with newman on Linux now?:

I need to be able to use newman from our CI/CD system to run collections. I don’t have service accounts established on our CI/CD servers. I used to be able to export/share my collection via a URL or as a JSON file. That is no longer an option.

I could possibly use the collection access key and use JSON files instead of links. However, there is no v10.0.0 for Linux. Am I missing something?

App Version on Ubuntu 18.04:

Try To Export JSON:

Update Button “Spins” Forever:
(progress bar just keeps scrolling…)

Looks like the option to use generate the key for a secure URL is available on the web interface, but not the Linux app. So at least I’m not completely blocked.
