We have a deployed a fix for the IMX Marketplace and have confirmed it is now showing all collections.
Due to an earlier issue with Github (see: https://www.githubstatus.com/
) the github API began serving the incorrect version for some repository tags.
We have deployed a fix for the marketplace to lock to the current version and we are continue to monitor.
In addition, our global CDN cache has been cleared (this may take up to 15 minutes to propagate through Edge locations)
