We submitted my wife's FLR(m) application online on 17th Sept 2017, so not too long after yourself.
Also received the biometrics letter just a few days later like yourself and the online status check also says 'Awaiting a decision'.
The letter we got through the post says they will make a decision within 8 weeks so I'm not expecting it any sooner than that, although I wouldn't complain if it came sooner
Not sure if that answers your questions but thought I'd comment as we're both in a similar position.
Btw, when you track the status online, which reference number are you using?
Only the IHS no. seems to be recognised for us - the rest come back as not recognised.
I was a bit worried at first, but I'm guessing this is just an issue with their (new) tracking system.
