Polling not working when a Union is used for a mount

What is the problem you are having with rclone?

Polling does not work (changes are not detected) when Union is used. When I use the remote Chunk: by itself in a mount I can see changes as they happen. When I use Union: which is a union of the Chunk: remote and an SMB share on my NAS I do not see any changes when I do an ls on the mount. I would just like to know if this is expected behavior or not before I do a deep dive into log files

Run the command 'rclone version' and share the full output of the command.

hi, based on forum posts and github, union should support polling

might try rclone selfupdate and test again.
might test upstreams = Chunk:

also, the command you are runing and debug log, were not posted?

Thanks. I will try removing the NAS from the upstream list and see does it detect changes. If not I'll come back with some log files.
