Hi there! It's possible that your opponent is using a combination of their abilities and smite to burst down the objective faster than your auto-smite. Another possibility is that your timing may be slightly off, as smiting requires precise timing and practice to master. It's also important to remember that certain objectives, like dragon or baron, have different health thresholds that trigger special effects when they're smited. It's a good idea to practice smiting in custom games or in training mode to improve your timing and get a feel for each objective's unique properties. Good luck on the rift!
