We’ve received some reports that newly added Local Files aren’t syncing with the phone and either do not show up at all in the playlist or even if they do appear to be correctly downloaded they still don't play.
We can confirm the right team is aware of this and is looking into it. If you’re experiencing this issue, make sure to follow the instructions in the Status Update below, add your +VOTE and subscribe to this thread so that you'll be notified as soon as there are any updates.
Thanks for reporting this and providing us all the relevant info.
We've passed your details on to our developers and they have already rolled out a fix to improve the experience reported.
We are aware that some users still have trouble syncing their local files with their iPhones, but this seems to be affecting specific devices or setups and requires individual troubleshooting - It'd be great to follow the steps you'll find here under Didn’t work?
We’d also recommend you try a clean reinstall, which will remove any corrupt data from your device. Just a heads-up, this will remove all your downloads and you'll have to download everything again.
If that doesn’t do the trick, you can post in the relevant help board and we’ll see if we can think up some other things to try.
