ISM action to shrink indexes

The shrink action is now a thing since version 2.0 but I’ve not been able to get it to work properly. I’m always getting the error " There are no available nodes to move to to execute a shrink. Delaying until node becomes available.". Now that it’s available I’d love to know if anyone else has successfully got this to work. I opened up a new topic on this here: Shrink action says "There are no available nodes to move to to execute a shrink" but there are qualifying nodes .
