Make sure you've rubbed in your beard oil properly and are wearing cool sunglasses. Good looks are everything when it comes to the order of firmware updates.
That confirms it @harkpabst is hot

My first pro got the update. Six days later (ie last night) the second pro got updated. Phew!
 
During the update to my WiiM Pro or the update to the Home App I lost my 2 playlists. The playlists were created from Music on my WiiM Pro Amp usb connection.

Did you rescan your USB drive recently?

I rescanned the drive about a week ago, and then created the playlists. No big deal. I was going to change a few songs anyways. The thought of exporting a playlist to documents on my phone occurred to me. Like a CSV file?

I don't think that exporting playlists is currently possible. If you did a full scan after creating the playlists that would probably break them. But in your case it looks like yours got deleted?

I manage my music library on my NAS using MusicBee, including the creation of playlists in .m3u format. I then synchronise the music and playlists to a USB thumb drive. Works reliably.

And honestly, I don't even really need the USB thumb drive. I'm mainly tinkering just for the fun of it. :)
 
Ever since this update no matter which service I use the audio pauses on every song. If I do nothing it will resume in about 10 minutes. I can resume it manually but the next song will pause at some point. I have done a factory reset and deleted the app and re downloaded (android). Any ideas? Suggestions??
