This function isn’t working at all for me any more. I’m having to make an eraser block & using subtract instead, which is kinda tedious.
It is a bug that came up with version 3.0.3. It will be fixed in an upcoming release.
Any idea when the update will go live?
Another potential bug is that all my workspaces are black when I open them for the first time, as is a new workspace. It reverts back to normal if I close/open again
Next week. It is already fixed, update will be submitted to the App Store next Monday.
Are you running on iOS10?
The black screen bug is gone on iOS11.
