Apple's Messages app is a total dumpster fire. Literally every other chat platform out there has figured it out. Snapchat, Telegram, FB Messenger, WhatsApp, Line, etc., all work just fine across platforms. Only Apple wants it to suck for their users whenever a non-Apple device enters the conversation. I can't understand why people willingly subject themselves to that misery and still somehow feel smug about their iOS echo chamber. Pathetic.
Out with the old, in with the new...
