Even when I use the preview option, the post still appears without a thumbnail. When I share the same link in other Nostr apps like Amethyst, the thumbnail preview shows normally. So I’m trying to understand why this is happening in Yakihonne. I would really like to use Yakihonne as my default Nostr app, but the missing thumbnails make it less atractive to share then. Is it the relay/server where media get uploaded?
