No. Check the actual official case record and communications instead of inferring the absence of requests from a private inbox.
Use the real instruction and response date
The published process calls for timely completion of requested material. Address an access issue promptly through the applicable process; a contact problem does not automatically extend a deadline or guarantee a fixed residence date. Test the assumption directly: the absence of a message in a mailbox you can read is evidence about that mailbox, not about the case.
The case may have an open request whose response period is running, and it may have had one for weeks. The correct first step when contact details have changed is therefore not to wait and see but to look at the official record, because the only reading that settles the question is the one taken from the source holding it. Where a request is found and its period has been running, raise the access problem and the outstanding request together rather than one after the other; explaining why a response is late is a different conversation from asking for an account to be restored, and both are better had at once.
A deadline is set by the instruction that created it. It does not adjust itself because the applicant did not see that instruction, and no fixed residence date follows from any of this.
