I bought affinity in the hopes of being able to continue some projects on the go, but unfortunately it seems that nearly none of my existing abr brush sets are compatible. Of the 21 brush packs below, only 7 will even import. And then of those 7 any brush with a texture has a weird horizontal banding effect. Guessing which brushes will import also seems to be random. The BOKTUP.abr attached won't import and it's literally just hard round and soft round brushes.
I tried a couple things, from reinstalling the app to upgrading to IpadOS and none of them solved the issue. Leaving this here in the hopes that in the future brush support can be improved.
