A month or so back, the ❤️ emoji on my phone started showing up like this whenever I select it: ♥. The symbol in the emoji menu is still big and red; but when I trigger it (add to text), it appears black and smallish. The reason I was able to type the regular red heart above is because I'm on my iPad. It won't work on my iPhone. Now here's the kicker: I happened to switch to a new phone last week, and it's still happening on the new phone! (I restored iCloud backup from my previous phone.) Do I have to wipe / set up as new just to fix this weird little problem, lol?
