 - Your JF busy, too slow or is already refreshing another library and is not picking up the folder in time.
 - JF doesn't have the permissions to see the folder created by the extension.
 - You didn't mount the volumes as expected and JF is looking in the wrong place.

-## Migration problems
-Due to the filesystem change between Tube Archivist v0.3.6 to v0.4.0, this will reset your YouTube videos in Jellyfin and will add them as new again. Unfortunately there is no migration path.
-
-To import an existing Tube Archivist archive created with v0.3.4 or before, there are a few manual steps needed. These issues are fixed with videos and channels indexed with v0.3.5 and later.
-
-Apply these fixes *before* importing the archive.
-
-**Permissions**  
-Fix folder permissions not owned by the correct user. Navigate to the `ta_video_path` and run:
-
-```bash
-sudo chown -R $UID:$GID .
-```

-**Channel Art**  
-Tube Archivist v0.3.5 adds additional art work to the channel metadata. To trigger an automatic refresh of your old channels open a Python shell within the *tubearchivist* container:
-
-```bash
-docker exec -it tubearchivist python
-```
-
-Then execute these lines to trigger a background task for a full metadata refresh for all channels.
-
-```python
-from home.src.es.connect import IndexPaginate
-from home.tasks import check_reindex
-
-query = {"query": {"match_all": {}}}
-all_channels = IndexPaginate("ta_channel", query).get_results()
-reindex = {"channel": [i["channel_id"] for i in all_channels]}
-check_reindex.delay(data=reindex)
-```
