weird cohort behaviour (time lag?)

[John Lenton]

$ COH=$( snap create-cohort kubectl | jmes 'cohorts.kubectl."cohort-key"' )
$ snap install kubectl --classic --channel=1.16 --cohort=$COH
error: snap "kubectl" is not available on 1.16/stable but is available to install on the following
       tracks:

       latest/stable snap install --stable kubectl
       1.15/stable snap install --channel=1.15 kubectl

... wait a few minutes ...

It seems to actually be intermittent, not specifically lagged.
