@jonas when is this likely to be? as i'm not happy going through the Windows mixer as it ruins the sound.
I'm quite happy to test out beta versions if you want a tester?
As it stands now I have bought the latest version which gives me no benefit than to the last free one for my use case.

I'm not sure if that happens with a particular album or all of them. And the text of the error may help someone to figure out what's happening. What is it?

Just a couple of tips adding to the suggestion by silver-sun (which is the safest for important playlists, since an external file will survive an eventual database corruption):

Use Undo to fix a mistake during the current Strawberry session. Keep in mind that the undo history will be lost if you close the player.

We have starred (favorite) playlists, which are kept in the sidebar tab "Playlists" after being closed in the playlists pane (so, there's less chance of spoiling them), and are updated on the fly when open, like regular ones. To add a favorite, right click on the playlist tab and choose "Star playlist"

You may find the combination of external, regular and favorite playlists that suits you best. For example, an external as backup to save every now and then plus a favorite (even also a regular one). Or two favorites: a do-not-touch version for reference/backup and another one to play with safely.

This issue is still occuring on 1.2.10.

@sissou To do just that, I wrote a simple script:
https://github.com/SirYaro/scripts/blob/main/strawberry-play-random-album.sh

For sure, it is not an optimal solution, but it works fine for me for a couple of weeks now.

@Darkness-Twisty
It works here with the latest release 1.2.11, if you got an option for "OAuth", it's an older release of Strawberry, the latest OAuth is always being used.
Strange errors might happen if there is a incompatible client id used.

I figured out how to fix this.
I inststalled DB Browser and it allowed me to edit the database and remove the items that no longer existed.

I know this topic is quite old but I'm having the same issue today but the "offline mode" setting is unchecked/disable and yet it still doesn't scrobble, what do I do when that is the case?

(I'm running Strawberry on NixOS however, no flatpak)
