Problem with the Font Manager

Hello,

I believe there is an issue with the GeneratePress Font Manager. I access it via Appearance > Customize > Typography.

My version of GeneratePress is 3.5.1. (wp fresh install, no plugins)

• I cannot add a font without linking it to a Typography. If no Typography is linked to the font, the font is not saved at all when I save changes.
• It is also not possible to add multiple fonts, regardless of whether “Use Google Fonts API” is checked or not. The issue seems similar to the one described in this thread:
  “https://ww.wp.xz.cn/support/topic/generatepress-font-manager-issue-unable-to-add-multiple-fonts/“

After some testing, I noticed the same issue occurs with GeneratePress 3.5.0.
However, everything worked correctly with GeneratePress 3.4.0; there were no issues with that version.

Thank you in advance for your help.
