New S9+ not showing album art after transfer from Note 5...

[eppst1]

Hello! I picked up an S9+ today and used the smart switch app to move all my data from my Note 5 to my new phone.

After moving all of my music, only about 30% of my music has the album art attached to the files. While on my Note 5 100% of the music had album art.

I tried adding the art files to the phone but that is only working about 50% of the time.

Any idea why the album art didn't transfer correctly and why it's not showing up on my new phone?

Please advise!

Thanks in advance,
Ed
