If it helps, I’m also experiencing an issue where the site fails to load fully but on macOS26.

Initially fonts will look off, sections won’t load. Then minutes later, the whole thing renders correctly.

Yeah in my case no text loads, just some symbols. Not sure wtf is going on but it’s super annoying.

Super strange, all the sudden it started working again. I tested a lot of things, nothing fixed it. Not sure if it was a temporary bug, but it works for now.
