I use amethyst on android. But I've been having issues with Nostr recently. I tried to post something and seconds later, it had just been removed, like gone, deleted. I hit post, I watched it post and appear in the feed, I checked by logging into a different account, there the post was. And then. Gone. No idea if it was removed or something, but I didn't think Nostr had mods who could do that.
