Hello,
Same problem no textPreview in Glyphs 3.1.2, any solutions ? Macbook M1 Ventura 
What specifically so you mean.
The thread is about the extra TextPreview app. That has not so much to do with the Glyphs version.
Sorry Georg, quite a newbie here.
You’re right, it’s not about the Textpreviewapp but the feature in the window menu of Glyphs 3. Is there a topic about that?
Moved it to a new thread.
What specific problems do you have?
Just set-up the export in the font info, everything is alright by now.
Thank a lots, You’re so reactive 
And yes i will double check all my question before posting here, sorry
