Customise highlight only working on some posts?

[AmyFarrahFowlerCooper]

Reading some threads and the OPs posts aren't all highlighted. The odd one or two are then the further I get into reading the thread, it suddenly stops. Definitely still logged in too. What am I doing wrong MNHQ? :)

Oh, that sounds odd.

How are you viewing MN? On a phone or computer or handheld device?

Its on my iPhone. Its not happening on every thread just the odd one or two :)

OK. And are you using the mobile version of the site or the app?

The mobile version :)

OK. We'll take a look.

Do let us know if anything changes (hopefully for the better).

Thanks :D
