oh sure, do you happen to know if this is also the case for older affinity versions like affinity photo 2 (pre canva taking ownership and reinventing it).

I tested today. I was able to import the ABR to Affinity Photo v2 using the normal Import brushes feature and they work with the brush tool.
Instructions: Open Brushes-panel > Panel menu > Import brushes > Select the ABR file you want to import (you'll need to unzip the downloaded zip archive first).
