Jetpack activation broken when using changed admin url

When activating Jetpack, the service not the plugin, it redirects to it’s admin page but uses /wp-admin in the url and results in 404.

For example, I change my /wp-admin to be /my-admin using this plugin and check the option to block access.

Then I install and activate jetpack plugin and from the jetpack authentication screen provide my details (email/API) which do indeed authenticate but then it redirect to it’s settings page:

/wp-admin/admin.php?page=jetpack#/dashboard

Rather than:

/my-admin/admin.php?page=jetpack#/dashboard

Is this something I should report to jetpack, i.e. not doing something the wp standard way or is this unavoidable because jetpack isn’t aware of the new htaccess rules?
