Is there a way to get Smart Playlists to work with iOS and iTunes Match? I'm an iTunes Match subscriber, and since I signed up, Smart Playlists haven't been working in conjunction with my iPhone.

I have several Smart Playlists and each one has a song limit.
On my iPhone, the Smart Playlists completely ignore the limit, which makes them sort of useless, because I can't download a playlist without filling up my phone.

It also seems that my Smart Playlists aren't updating, even though they're all set to "live update."

Is there a way to get Smart Playlists working with iTunes Match and iOS?

My recently added and recently played playlists were my way of keeping my phone up-to-date without having to manually manage my music. Not having functional Smart Playlists is a pain.
There are a couple of potential solutions to this problem. I say potential because everyone's listening habits and needs are different, so your mileage may vary. Here goes:  

The Smart Playlist problem is not new, and certainly not unique in your case.  There seems to be an overall problem with Smart Playlist syncing through iTunes Match (1) across different devices, (2) with any expediency (usually takes >= 48 hours), and (3) with respect to honoring certain rules (e.g., number of songs allowed).  Another common theme seems to be that "nested" playlists cause even more of a problem than standard Smart Playlists. Nested lists are those that are created when you use your option key to turn the + into an ellipsis (...), which creates a sub-rule for your master rule. 

Solution 1: Dumb it down


  Create a standard playlist (Dumb) and give it the same name as your Smart playlist. Copy the content from Smart to Dumb. Sync your device, computer, whatever. Rinse, wash, repeat for each Smart Playlist you want to have properly represented on your other devices. This works. 


Solution 2: Really Dumb it Down  


  Do your best to avoid the aforementioned nested playlists. This may require you to build several smaller smart playlists with limited criteria. Not the easiest workaround, but we're going for functionality here, right? 


Solution 3: Really make your "Recently Added" folder songs that are "Recently Added"    


  For your "Recently Added" folder, tack on just one more rule to force songs added after a date, rather than only within the last two weeks (see pic below)  


  

So, I hope this gets you at least a little closer to your goal. I tried to add as much info as I could here since, one more time: everyone's listening and categorizing habits are different :-)
You may find other variations on these, but do realize that, at least for now, this is a server-side problem and workarounds like these represent the best available solutions.
