It took me a long and frustrating journey to understand why after upgrading to Ventura and now to V2 suite of affinity, suddenly most of my projects started to complain about missing fonts that I didn't even intentionally installed.
Turns out I was using a lot of Apple fonts or other fonts I added long time ago that are now Variable.
Because many of those fonts are not available as TTF I have now to start looking for alternatives, going back to design stage of a project that I thought was print-ready and small changes to old layouts now mean having to spend hours of research for a similar-looking font.
And what is more frustrating is to know that, if my documents were made with Adobe, I wouldn't have any problem with the fonts now.
This also made my font selection much more restricted as now, from my operation system, the compatible font library is much more limited and I need to spend time and money to get alternatives.
