Facebook App Mis-Attributing Posts To Other Users?

Maybe it was just a glitch in my app, but this morning I received a notification on my Facebook App that Sara had commented on a post (why I got this notification I’m not sure, as I was not following the post) – only to click through and see that it was her own post, except it wasn’t.

The Facebook app was displaying someone else’s post from 19 hours earlier, as Sara’s from three minutes previous.

Here is what I saw on my phone.

Here is the original post from 19 hours previous.

This issue was not occurring on the website version. Has anyone else experienced this in the app today or lately, or is it a glitch confined to just my app?
