When setting the settings, the camera will not go past (faster than) 1/200 shutter speed in multiple modes including manual, Av, and Tv. Thank you!
Are you using flash? The max shutter with flash is 1/200, you need to enable HSS if that is the case/option. If you have nothing in the hotshoe you could try a camera reset.
You were right, thank you so much! When I put the flash down it easily changed speeds. Thank you again!
