The User Experience Guide seems to be out of date at least "Appendix B: Font Specifications".
Latest UX Guide included in SDK 3.0.9 is missing fonts specifications for at least to Edge devices: 1030 and 130.
Moreover, in the case of the Edge 130 I believe some fonts sizes are not available or are rendered the same as other sizes.
Can you please update the UX Guide with the missing information so developers will now which fonts are available on which device?
Thanks.
