Camera covering the entire area

Ok, I give up. I've been at this for hours. I need some detailed help.

I am using the camera to create a funky/cute background for 1 level.

It's a maze and a ball goes through the maze. Very simple. I setup the camera to activate. That works.

The game size is 2560 x 4352, the Viewport size is 1280 x 2176.

I need the media (camera) to cover the Entire viewport area and/or move around the maze with the ball.

The ball has the 'scroll to' behavior.

I have the camera covering the entire game size, but I've tried it just over the viewport area.

It doesn't seem to matter what I set the preferred width & preferred height.

I set the background layer (which is the layer with the camera) to parallax 0%, 0% and 100%, 100% - neither worked.

Please what am I doing wrong?

I have tried several combination, but every combination I try just makes the camera a little box that doesn't cover the entire area.

I'm so frustrated. Please help.

Hi, from what I understand, your level has a large height and you want to show it integrally, that's right?

I only want to use the camera as a background in level 3, maybe on others from time to time, but for now only on level 3.

I kind of figured it out, but only because I gerry-rigged it. I grabbed the handle on side and stretched it to make it huge. Now it works, but I'm thinking that gerry-rigging will cause issues in the long run. I'd rather do it right, you know.
