It will not be a problem if it is more than 30 days. We just got passport request on jan 21st. We submitted everything mid sep, nov 25th they requested a new biometric saying the quality of the first one was not good. I sent a web form to negotiate not repeating the bio on jan 3rd and ecas showed decision made on jan 17 (so the negotiation worked)
Just wait at least for a month now that you submitted everything. Make sure you check mycic at least once a week. The repeat bio request was only sent to mycic and was not emailed at all.
What did you write to them if I may ask?
