Thanks a lot for large playlists correction in Deezer!

Has anyone received this update yet? I always considered myself a privileged user, but apparently they forgot about me.

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's what I finally did last night and got my update right away! Sometimes the solution is just too obvious.

That confirms it @harkpabst is hot

My first pro got the update. Six days later (ie last night) the second pro got updated. Phew!

I'd definitely start worrying if one of them was two versions ahead ...

Yes I had that same thought. Thankfully it turned out for the best. It was unusual because normally both pros get updates at the same time. But maybe that process has changed now. I know now for future updates.

Both my Pros received the update yesterday. It isn't listed but the update also fixed Qobuz Connect, which seems to work just fine

At the bus stop you just need to light a cigarette and the bus will appear right away.

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?

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.
