I can turn out work in most formats now without breaking a sweat. But the second a platform has its own odd specs, I get tangled. I send something over, it bounces back wrong, and I'm digging through fine print again wondering how I missed it.
More people experience this than they realize.
You can handle most formats, but the platform-specific rules still trip you up.
If this sounds familiar, the Library can help you find the bigger picture.
