Kerning alternative not showing at home 2024

Hi there. First Time fontself user, big fan. Love the product

So I wanted to try to do alternative glyphs for my typeface and at first, when I did the kerning pairs, it seemed like it was a done deal. It was kerned to the glyph.

but when I went to the home screen of Fontself, it didn’t show up in the preview

Now I have read the previous posts on this issue and they were from 3 years ago stating it was due to the extension being developed on Chromium so I was wondering if there have been any developments on patches or free upgrades to resolve this bug.

Let me know if there are any quick fixes or current fixes on this matter and thank you once again for Fontself
