Ask HN: Are Google Play links being auto-shadowbanned on HN?

I submitted the URL to an app on Google Play for "Show HN", however the submission never showed up except when I'm logged in using my account and no discussion/comments link shows up. On the other hand, the submission is not marked as [flagged]. Are links to Apps on Google Play disallowed on HN? If yes, I can't say I blame HN, I just wasn't aware of the fact.
