My autoplaylist below is nothing exotic. In the past (a few days and versions ago), MB would auto-refresh the playlist in the following scenario:
1) Select tracks in the inbox to import into my MB library (only 1 library)
2) Organize files (add to library is checked)
3) Select the genre autoplaylist the newly imported album is likely to be found
4) See newly imported album in autoplaylist and listen
Now,
1) Select tracks in the inbox to import into my MB library (only 1 library)
2) Organize files (add to library is checked)
3) Select the genre autoplaylist the newly imported album is likely to be found
4) Delete autoplaylist or modify autoplaylist (i.e. remove a criteria)
5) Recreate autoplaylist or re-add removed criteria from step 4.
6) See newly imported album in autoplaylist and listen
It appears that there's these .snap files in under the playlist folder that don't get updated when a new album is imported into MB (modify date timestamps don't change since the time starting up MB [is this why MB appears to have slower startups these days?]). I never noticed these snap files before because I never had any reason to check the playlist folder under file explorer in the past several months.
