In my exported variable font some parts are not interpolated while others are.
In Glyphs the preview looks good and anything seems to be perfect compatible.
The static export of the font is fine too. There are also no error messages at the export of the variable font.
I made a screen video from testing in Dinamos Font gauntlet and a screenshot in Glyphs where anything seems to be fine. The upside down exclamation mark is the standard one just added as a component and flipped but still the parts that are not properly interpolated are different in both. Same for the brackets, the original left bracket is not interpolated but the right one which is just a component of the first one works. Very strange…
Thx & Greetings!
