Rob from FontStruct here.
Recently I’ve noticed this dialog appearing when opening .glyphs files exported from FontStruct.
To get a working font in GlyphsApp I have to check all and then “keep selected”.
Maybe I can update the export code to avoid this – any suggestions or doc for that?
Version 2.5.1 (1141)
PS: In the text at the top “… an older version …” and “you would like”
