Lock-on mechanics are bugged since season 4

Locking onto vehicles is completely bugged with various problems.                                                                                                                                                                                                                                                                                                                 Examples:

Attack helicopter gunner lock-on is hardly working. If you lock onto a vehicle and shoot the missile, then switch to guns, and then back to lock-on, it will not lock onto the vehicle even though you have a missile ready.

The locked-on (red) indicator is not clearing even if you've switched weapons, as if the target is painted. This looks like some screw-up in the coding between the painted and locked-on mechanics. Sheesh, DICE, creating problems that were never a thing. This is a big issue since ducking behind cover like a building, rock, or hill, you are still seen by the person targeting you. This is affected in vehicles, aircraft, and infantry lock-on capable weapons.

I had an instance in the Attak helicopter where I was using Air-to-Air lock-on missiles, and when I switched to rockets, the lock-on did not clear, but when I switched back to Air-to-Air, the lock would clear but would not try to lock on to the enemy. Then, when I switched back to rockets, it would show the lock-on symbol again.

Serious question for the DICE devs: How do you keep screwing up this badly with every single update to the game?
