I Have Never Seen Sony/Viacom Channels Doing So(Cutting Scenes/Songs) But Yes Zee Is The One Who Does So With 90% Of Its Movies. They Cut The Pre-Credits And Post-Credits Of Most Of The Movies. They Show Pre-Credits And Post-Credits In Those Movies Which Are Either Produced By Zee Studios Or They Have Got Rights Of Those Movies As A Part Of Deal(Eg. Dangal, Secret Superstar) And After Star Gold Was Revamped And Star Gold 2 Was Launched In February 2020, They Also Stopped Showing Post-Credit Scenes And Show Movie Promos Now(Except For YRF Movies)
