Income not shown on HMRC app

I started my current job from 13/05/2023. I get paid weekly and I am sure I have paid tax and NI according to my payslips. It has been more than a 1 years but still I can’t see any income or tax showing on my HMRC app. even i recevied a P800, thats also not shown my current job and i think i have overpaying my tax on 2023/2024, i have contact HMRC before and the problem still not fixed.
