Upgrading the vault charm from charmstore latest stable revision 54 to ch:vault 1.7/stable fails

The vault channel was configured as stable on the charmstore charm, which apparently goes to tracking: 1.10/stable

Changing the charm to 1.7/stable changes also the tracking to 1.7/stable, trying to downgrade manually (I don't think this is a good idea at all):

snap refresh --amend --channel=1.7/stable vault
error: cannot refresh "vault": snap "vault" has running apps (vault), pids: 212762

service vault stop followed by the refresh command works fine.

Traceback:
