Friend feed is not populating anymore

[backbone1105]

Desktop-version.

Suddenly (a week or 2 ago) the friend feed is not showing activity anymore of the Spotfy-accounts I follow.
I'm sure that one of the accounts I'm following has recent activity (it's my daughter), but her activity is not coming up in the feed.
Is it possibe that it has to do with the following : recently someone logged in on my desktop to FaceBook with their account. Afterwards we explicelty logged-out of Facebook. Is it possible that there is some leftover from this Facebook-session and as I personally do not have a Facebook-account their is somewhere a mismatch for the Friends-feed ?
