xAutumnAngelx is this by any chance since the Deck the Palms Event started this week? Because my cursor is going off after claiming rewards, then again once I'm in the game. It stops doing it once I've powercycled the console and restarted my game. Toggling the cursor back on (with the button with 2 squares on the left hand side) works from the Sims homepage but not when it disappears in the game.
So if it is after claiming event rewards I'd suggest restarting the console after claiming instead of going straight into your game.
If not I'd check that your console and controller are both up to date. The console doesn't always update the controller automatically. Go to Profile & system >Settings >Devices & connections to update the controller. You could also try reinstalling your game if you didn't do that after your last issue and clear your locally saved data by selecting Sims 4 on your console home screen using the menu button (3 lines) go to Manage Game and Add-ons>Saved Data. You'll see 2 sets of data, pick the set next to your gamertag/username and select delete from console only (this step should be carried out while the game is not running). Then immediately load up your game and it will sync up with the cloud and retrieve your data.
