Quick reply gone / subscriptions

[robvalue]

This morning I noticed the quick reply box which is normally at the bottom of threads I'm viewing has gone. I checked my options and it's still ticked to be there.

Perhaps coincidentally, there's a new subscribe button at the bottom on the mobile version. When I press it I get two options, no emails and then a blank description for the second option. In full mode, I still just get the one option of no emails. Does subscribe to thread actually do anything if you don't get emails?

I just noticed that there are also subscription options when replying in the mobile version, including a correctly labelled emails option.
