Cant increase font size = cant read

I thought Id use this app to read the magazine, since the magazine has such a small font size that I find it difficult to read. It turns out that doesnt work, because the font size on this app is small too and I dont see a way to increase the font size! It wont even let me zoom in! Ill have to cancel my subscription which I hate to do because I enjoy it, but whats the point if I cant read it?
