Yes, I have tried to import the brushes using 3 methods:
1. First, I directly used Airdrop with my mac. This is how I usually do it, as Procreate will automatically install the brushes. But my iPad installed the brushes on Affinity Designer instead (no selection for which app i might prefer to import it either)
2. Then airdropped them as a zip file and unzipped them on my ipad, then tried to drag and drop them into Procreate. the files would bounce back, as Procreate suddenly was unable to recognize the brush files
3. Finally, I used the Import button on the top of the Procreate app, but as you can see in the picture, Procreate suddenly automatically assumes .abr brushes belong to Affinity Designer (the logo on the brush file was never there before i downloaded Affinity Designer)
This is quite troubling, as I enjoy both of these art and design apps. Thank you very much for trying to help!
