How to smooth corner spackling the easiest way?

[Cheesen]

with a metal profile embedded in the corner, there wouldn't have been any mark at all.....

Oh yes. There would have been a white mark. And it would be visible from 100 meters away on the green wall. I have a metal profile embedded in all corners, and I know exactly how sensitive the corners are still.
Now I can fix it with 0502y standard white which is always at home instead of going to the paint store to mix a new can since the old one has dried.

Sure. There would have been a white mark, and it would have been visible from 100 meters away on the green wall. I have metal profiles embedded in all corners, and I know exactly how sensitive the corners are anyway. Now I can fix it with 0502y standard white that I always have at home instead of going to the paint store to mix a new can since the old one dried up.

There is a bit of a difference between metal and metal, the ones I linked to are steel, but for example, Biltema has them in aluminum, and they are usually dented already in their rack.

Yes, I did set steel. It was completely impossible to adjust where the corner wasn't exactly 90 degrees

I used Aquabead but found that it adhered poorly to the wall, so I glued it with wallpaper adhesive. And then applied joint compound over it.

Oh, I thought so

I used Aquabead but found it adhered poorly to the wall so I glued them with fabric adhesive. And then putty over it

Oh really? I think it worked perfectly. Make sure the corner is vacuumed and dust-free. Spray a generous amount of water on the trim with a plant sprayer. I'm not in a hurry to press the trim but give it a minute for the glue to dissolve. Then just press and rub a little along the entire trim.

I have tried another plastic trim that was supposed to be attached with drywall screws but it was terrible. It became wavy between the screws and it was difficult to get the putty to cover properly. Needed to screw every other cm to keep it tight against the wall.

isn't it difficult to get it into the corner without the tape sticking first?

No, it's no problem. The glue doesn't grip.

It's not unlikely that it was user error on my part. With extra glue, it became foolproof anyway

It's not that important. Instead, install a decorative trim; the corner withstands kids and loud parties and looks much nicer.

I have eleven outer corners in the house and would probably go mad if they weren't trimmed.

In the picture above, you can see typical damage that would have looked terrible if it was plastered and painted, but now it's barely visible in the trim and easy to fix.

feels like a 70s solution.

If aluminum doesn't hold up, maybe one should start considering how they utilize their home...
