I am new to this group
I would just like to get some peace of mind regarding FLR M (first extension after 30 months). I have posted my application on the 24th Sept, received by HO on 25th Sept, payment taken on 26th Sept. It has been 16 days and i still have not received acknowledgement and bio letter? is this normal or should i be expecting it within this time frame? I could use some reassurance

Thank you
