I am having a hard time getting the hang of affinity photo for the iPad app. I find simple functions very difficult to locate! What I am trying to do right now is draw a diamond with SHARP edges, or even a pen line with square ends instead of rounded ones. Even with the sharp node option or sharp function with the rectangle shape the edges are still very rounded and not ‘pointy’. Am I missing something here?

This is driving me nuts and I'm sure its an easy solution but I'm new to affinity designer and I cannot find the answer anywhere. When you select an area using the selection brush tool, do your thing and then want to select a new area separately or just get those annoying dotted lines to go away, how the heck do you do it? I can't get the selection area to go away unless I CMND Z out of everything I've done. This is so dumb and I'm frustrated!
