It looks like Glyphs 3 does not generate ligature carets in GDEF table, but Glyphs 2 does for the same file. Is this a general issue or something wrong in my file?
There seems to be something wrong in Glyphs. We’ll have a look.
This is fixed now. Thanks for the report!
Thanks, I confirm it is working in the latest update (if anyone is wondering, TextEdit and possibly other Apple apps seem to use GDEF ligature carets).
