Shortcuts Glyphs: Are they bundled with the app as images, or are you just using SF Symbols? If they're just SF Symbols, then you can probably delete them; if they're images you've bundled, then you might want to find a Shortcuts or Apple license and put that in. A custom-written "I don't own them" comes across as rather unprofessional, since that's not exactly what they're licensed under.
Firefly: good, except the license is long enough that I can see that the view containing the license text doesn't quite go all the way to the bottom edge. It looks a bit odd when the license text disappears into space that has the same color as the background of the license, but has no content.
