Re: Camera Angle Issues

You probably have some preset camera states (useful to simmers who record videos).  Try deleting the VideoCameraStates file in the folder of the same name within your Electronic Arts/The Sims 4 folder.  Don't worry - the file will be recreated automatically when you restart the game.

Edit:  and yes, CTRL+9 and CTRL+0 can be used instead of just the numbers.
