Is it a bug when i create a design on macOS then open it in iOS and it looks different?
Fonts are different sizes and in different positions... and formatting (text color mainly) doesn’t stick?
Why are the macOS and iOS files different?
Is something not working like it should? Let us know.
The first thing that comes to mind is that certain fonts might be missing? If not, this is probably a bug and shouldn't be happening — if you could share a few sample files with us at firstname.lastname@example.org, we'd check what's going wrong!
