Glitch in "Subscribe" Function?

[Feeble Wonk]

I might have found a bug in the subscribe function of the updated PF format.
I'm easily able to subscribe to a thread in the general "browsing" mode. However, when I utilize a specific search word to narrow my browsing options, the bar with the subscription star is lost and there is no "subscribe" option available in the drop down menu.
Am I missing something?

I prefer the iOS app whenever possible. That's where I found the glitch.
