Some plugins fix this but when a user joins a server, a chat message in yellow says that "<name> joined the game" and this only appears for other users as the chat loads client side after this message is sent and client side users can't see the entire chat history of a server so this message isn't visible. I'm not 100% sure this is a bug but iirc the yellow message shows up on Bedrock so this is technically a parity issue.
This doesn't classify as a valid parity report as this behavior predates the busy bees updates.
Seems intentional to me; it's an announcement for everyone, but you obviously already know you entered the server, so there's no point in telling you.
