Playlists won't sync among computers

[2b2a]

I just started using Spotify on two of my laptops, my phone, and tablet. I added about 400 songs to a playlist on one computer one night, then around 6000 on the other computer the next. Initiallly, it synced the first 400 songs from the first night. When I checked if the 6k songs synced, I found they were not there. I have tried logging in and out, restarting the program, the computer, and switching between available offline mode on each playlist. Is there anything I should do? The computers have been on all day, so it would not be a problem with not having enough time to sync. The phone and tablet both show the 6000 songs.

Hi, and welcome to the community!

If you are trying to sync all 6k songs on those devices:

Please note that on Spotify Premium the syncing limit is a maximum of 3,333 songs per device. There is also a limit of 3 devices that you can have synced tracks on.

There is an idea to change this here.

If you haven't exceeded these limits, I suggest you reinstall Spotify; and when syncing on one device; don't have another device with Spotify on at the same time.
