Current issue

App Versions are not displayed using the future admin.atlassian.com "manage apps" experience

With new app releases this option should start showing but this is still an option with APp that have not been getting any recent updates.

This option is fully available on the old experience within Jira 'Manage Apps' section, where you can see the versions for the app see attachments and this App is developed by the same customer.

This is an issue because the app management experience will now have a new home within Connected Apps and current in-product experience via the Universal Plugin Manager (UPM) will be progressively deprecated.

Jira Manage Apps Section example below: 

New Connected Apps section for reference:

Workaround for partners or clients creating their own apps

Partners can release a new app software versions with the script

editionsEnabled:true

 Then, get it approved. Once approved, it will start showing in upcoming versions.
