Hello blue_Shift,
Sorry for the inconvenience you're experiencing.
To effectively use a Google Font within SP Page Builder, it needs to be added directly through the SP Page Builder interface. Simply including it in your template's <head> section won't make it available within the builder's font settings.
You can find instructions on adding custom fonts in SP Page Builder here:
🔗 SP Page Builder Font Book Guide
Please be aware that in SP Page Builder 5.7.1, there's a known issue affecting the addition of new fonts. This has been resolved, and the fix will be included in our next release.
Thank you for your patience.
Best regards
