Font Creator 15 Variable Font Slant Issue

Hi! The variable font slant axis is not working. I thought the problem might be with Affinity Publisher and reported it to them. However, Affinity people said they checked the slant axis and the font they tried worked. Can you fix the problem? Thanks.

I looked at the video, and noticed the slant axis works like a toggle in Affinity Publisher and like a true slider in your web browser. Please confirm this is the issue. Also have you tried with other software like Canva or InDesign?

I tested the font with Affinity Publisher Beta 2.6 and it works fine.

Good to know the problem is on their end and that they have fixed it!
