I remember once I was making a presentation using Google slides, I wanted to add an image when it told me that "webp format is not supported". Webp... Made by google... In google slides...

Ok, it didn't take long to figure out it was a language issue. I have now selected every possible language and the problem is gone, it took me months to fix it, lol. I do, however, see a problem with this language implementation

The same has been happening to me. Seems like accessing anything from lemmy.world is broken. I can open any post with hundreds of comments only to see a single one. The same happens with the sync app, as well as in a browser, though only at lemmy.world.
