My project looks like the images are low res, even though I don’t see any warning about photo quality.

This is actually a known bug within the software, and only affects some computers. Our project editor has not yet been optimized to work with the highest resolution/newest screens, so your project may appear to have low resolution. Watch carefully for the low-image quality symbol…it’s an exclamation point inside of an orange circle. If you don’t see that symbol anywhere on your project, you’re good to go! If you do see that symbol, you should fix the issue, which may mean choosing another image, or making the overall photo space smaller. This bug will be fixed soon!
