Photoshop canvas and artboard resize and export issue

Question

I'm new to design in general and I'm designing a prototype for the web.I'm creating my files in photoshop and exporting them into invision. When I export my files from photoshop into invision, they appear far too large in the browser.

The dimensions I want are 1920 x 1080 px. The artboards I'm exporting are the correct size (1920 x 1080) but when I export them, they're exporting as 2944 x2144. Photoshop tells me that the canvas size is 2944 x2144 but whenever I try to change the canvas size to 1920 x 1080 px, my changes do not hold. Even though photoshop reports the canvas size to exceed the artboard size, I don't see the typical grid that appears when this is the case.

Is there something I can do in photoshop to correct the issue I'm having?

Here's a link to a gif of me attempting to change the size of my canvas

Solution

I just had something similar, I think. Not sure exactly why, but seemed the artboard had been linked to the canvas, which wasn't the same thing. Anyway, resolution was to right-click artboard, under the layers panel, and un-link or something (I can't even go back and check, as I know not what I had done!)

In the layers panel when I right clicked on my artboard there was an option to "ungroup artboard" and when I selected this I was able to achieve the sizing I wanted, thanks!
