FLR(M) seem to be low priority for them, many of us have been waiting months. Some of us were told they'd be reusing our biometrics but are waiting for more information. Others have opted out of reusing them and are waiting for more information. A couple people have been invited to do biometrics as theirs couldn't be reused and they were able to schedule fairly quickly (they are only inviting in order of application). We don't know what may change in the next month, but I would not make any travel plans until you have the visa in hand. The sooner you are able to apply, the better (28 days before meeting 30 months in the UK is the earliest you can, up until the expiry of the visa). Right now you just have to be patient and roll with whatever options are available.
