I made glyphs with a
.vert suffix for vertical Japanese text, and exported my font which includes automatically generated vert and vrt2 features.
Then it works fine on MacOS, but when I tried to install it in Windows, the dialog showed that it was an invalid font file and could not be installed.
It installed successfully when I downgraded the Glyphs3 data to Glyph2 and exported via Glyphs2, or manually unchecked the Active checkbox of vrt2 features and exported via Glyphs3.
Any help would be appreciated. Thank you!
