There are no specific delays but like everybody else, DWP staff may have to self-isolate due to their getting the virus or potentially coming into contact with it, so reduced staffing levels may have an impact.
The DWP quote nine days for a letter to reach the right department and it often takes the PIP2 seven days to get to the claimant so you are still in this window but I would give the PIP helpline a call to make sure that the form has been sent and when this happened.
