Here is an exercise for you to try:
Go outside after the sun has set and with your flash on camera, set the camera to Manual shooting mode and set your shutter speed to 1/60th, the f/stop to f/8 and the flash on TTL. Set ISO to 100 or 200 if 100 is not an option. Compose a scene so you see sky where the sun set and your backyard or similar. Focus on a subject like a person or object and then turn off auto focus on your lens so the camera is not looking for something to focus on in the low light. Now take the picture. Next adjust your shutter speed to whatever the in-camera meter suggests for proper ambient exposure and it might be something like 1 second at the f8 aperture. Take a second picture. Comparing the two photos, there should be no difference between the two as far as the flash exposure is concerned but the ambient light should be dark in the first picture while the second exposure, set to the cameras meter reading for ambient light, should have detail or proper exposure similar to the two pictures above.The content you are trying to access is only available to members.
