Thank you to both of you 👏

Hi Paul 😉
Thanks a lot. It works !

Thanks Alewan 😉
but in the meantime I found the solution !
For thoose who are interested, you have to create a mask if not, indeed its does not work…
So with the Ipad version :
-create a layer and create a black rectangle 
-go to the first menu (horny sheet) > Canvas> Transparent canvas so you can get a transparent background.
-create a mask
-With the gradient tool create a radial line tool or another one.
-save in PNG format.

I found it.
canvas > detach 
 

I found it.
canvas > detach 
 

A big Thanks to both of you

Thank you all 

Hi Stokerg,
Thanks to your reply I got it !
I did not save the picture at each time ("save a copy") in the menu with the horny page icon on the top left. 
I did it and so it works.
So that means that one have not to forget to do it each time.
There is no automatic backup with Affinity, right ?

Thank you DM1 
I works on Affinity Photo and I changed the layer into a  pixels layer and it works !

Un grand merci à tous les deux ! 

Thanks to you both  

Thanks to you both  

Thanks
I found the key.
The layer related to this issue was inside a group.
I opened the group and selected the layer and it was ok.

Thanks a lot DM1
