Queue doesn't restore when container restarted

[mtrolley]

I am a new user and think I have everything set up properly, but if I have queued items and restart the container they do not get restored. Here's the log when the container restarts:

AttributeError: 'DownloadInfo' object has no attribute 'playlist_strict_mode'

The host directory mounted to /config contains three files: completed, pending, and queue. The queue file modification time is being updated when I add a new URL, so it looks like it's being tracked properly, but not being restored properly.

same issue, but the reason is that the queue file formats of the new and old versions are different.
so, I gave up on the queue
