Since yesterday's update I am not able to pick any brush set (not even the standard ones like Airbrush), I just get the loading symbol and nothing happens.
I must admit, I have added tons of brushes in a big amount of sorted brush sets, and I have some brush sets that used about 10 seconds to load, but I cannot switch to other groups at all at the moment, regardless if they took short or long to load before.
I tried restarting the app, the ipad, opened different projects/images, but I can't pick any brush sets (switching to another brush in the currently selected brush set works fine though)
Edit: Also I can't cancel the app trying to load the brush. So no other touch or pencil gestures work, I can only watch the loading animation or leave the app
