Its working a bit better now. I finally got the song uploaded that I've been working on for a while. There was a bit of a lag between when my phone first showed them as uploaded and I was able to play them, and then when iTunes itself displayed them as being in the cloud. But yes, it does appear to be working better but not as well as it did before Thursday. For now though I'm considering this a success and will not think about it for a few more days, haha. This ordeal wiped me out.
If you're trying to upload something, and you look at them on your phone, if there's a spinning icon where the downloaded icon usually is, then hold tight, it might be working. Since I got what I was trying to get uploaded up, I need to not devote my energy to this in a bit. For any Apple engineers who might be monitoring this thread (doubtful though it is), it's still not working as well as it was. Mostly there's a disconnect between when it is actually uploaded and when iTunes say it is.
Also, it appears that right clicking a song and adding it to icloud music library doesn't work for me, but updating the icloud music library as a whole does. Which is funny because before Thursday it was opposite for me. Anyways, glad it has some semblance of functionality now, however the state of iTunes Match does not give me hope that the feature is going to be around for too much longer.
