Under PAYE Income Tax Summary, you can see (well I can) your updated tax code and new estimated taxable income on your state pension. If your SP still include the yearly increases, then "they" haven't applied the changes you requested. When I logged on to the HMRC app a couple of days after asking them to correct my SP figures, I culd see the revised tax code & SP estimated taxable income. I also got a message stating I was due a tax refund.
