Unable to paint orange line on a transparent pixel layer

[PitterPen]

Hi,

I would like to paint an orange line on a transparent pixel layer.  When I use the paint brush though, nothing happens, no color, nothing.  However, when I paint on the main image (below the transparent layer), an orange line is painted just fine (but that's not what I want to do).

Some info and things I've tried:

The new transparent layer is does not have a lock icon.

The new layer is a Pixel layer.  The new layer is above the main image layer.

I right-clicked 'Rasterize' on each layer just to be sure.

The 'Protect Alpha' box is unchecked.

I'm using a 32 size round brush.

Opacity, Flow, and Hardness all = 100%.

I'm using the Photo Persona in Affinity Photo 2.

If it helps, below I've attached a screen print of my Affinity screen showing that the 'orange paint' layer has nothing and is above the main image.

Also, I followed the steps of the first minute of this video where he just adds a pixel layer and paints on it, so it seems like this is something Affinity should be able to do:  

 

I feel like I'm missing something fundamental here...any help would be much appreciated.

Thanks

Hi @PitterPen,

Welcome to the Affinity Forums

If you select the 'orange paint' empty pixel layer at the top of the layers stack, what opacity value is shown next to the blend mode list please?

Many thanks in advance!

If I click on the 'orange paint' layer, it looks like the opacity value = 100%.  Here's a screen shot:

I figured out what the issue was - in Channels I had the "white" 'Composite Alpha' Editable switch turned off.  I was doing another tutorial and the video had me turning those off, looks like I forgot to turn them all back on.

Thanks for taking a look-

Great when the person who asked for help solves the problem and then lets us know what the problem was and what the solution is. It really helps others (me) who have similar problems.
