I just got this one and can confirm it works with Apple TV. Originally made for Switch so I"m glad Apple is supporting these now! Make sure it's this one as an older version of it does not work.
Works with iOS & AppleTV, but not MacOS
I bought this one and it works like a dream
TLDR: Fix it yourself or buy a new official controller/
This is a thorough Google Doc of cheap and simple aftermarket adjustments you can make to your pro controller. I've used it myself and I along with others can attest that it's been a big help that's held up under a lot of playtime. I'd recommend at least taking a look at it before dropping money for an entirely new controller.
If you're intent on not trying to save it yourself I suggest sending it in for repairs or getting a new procon/gc controller entirely. I don't deny that they can be pricey either in full or even just repairs, but despite that they're the two biggest controllers in Smash because the risk you run in buying 3rd party controllers is that high. Here's a $27 procon with many stars across many reviews which seems good but they're mostly right after first use by people looking for a quick fix, many reviews after some play talk about not charging anymore, inputs dropping, bad input lag, and drift (which we're trying to avoid to begin with). You're paying for a replacement that will itself need to be replaced except now with no repair services offered, and this is the case for a lot of the third party scene.
"You get what you pay for" very much holds true for Smash controllers, even if your repair request isn't covered under warranty there are many online accounts of people sending their controllers with success, and again you can try to repair it yourself for much cheaper. Call in anecdotal but I've never known much less met anyone with a 3P controller that wasn't older than a month or two or in good condition after that.
