RTA Hyderabad — RC renewal delay

Went for RC renewal of my car. Paid all the required fees online and filed the documents. Took the photo and when went to the inspection the police personnel said even before inspecting my vehicle that the insurance details were not updated in RTA m wallet app. Don’t know why that is required when I have the physical copy of Indurance.
Had to call insurance provider to update which they confirmed after 15 days.
Went back for inspection and now they said brake light not working, got it fixed and now they say in old RC vehicle body type is not correct so that needs to be corrected.
When the body type was same for last 20 years what is the point in changing it now.
I think they only do RC renewals if you go with brokers as they get their commission else harass the public with unnecessary checks
As I clear saw most of them got away even if reverse lights or indicators were not working properly as they went with brokers
