Update
It seems Bandcamp Website is only broken when we try and do a search, lookups are okay,
therefore if you have a Bandcamp Artist url field and a Bandcamp Release url field for your songs, and you have Bandcamp Match:For songs already fully matched set to Update Metadata Only then the task can update information from Bandcamp Match.
But note by default Bandcamp Match:For songs already fully matched set to Rematch if only Partial Match and therefore probably needs changing.

These Urls can be added by Fix Songs if the MusicBrainz match has these links, so if you run Fix Songs first and then run Bandcamp Match as long as you have For songs already fully matched set to Update Metadata Only and do not have Ignore songs already matched to MusicBrainz or Discogs enabled this allows these songs to be updated from MusicBrainz.
This also mean if you manually add Bandcamp Artist url field and a Bandcamp Release url fields then your songs can then be updated from Bandcamp, for example adding credits to the Credits field
In the current release this will not work for Various Artists albums because both a Bandcamp Artist Url and Bandcamp Release Url are required, but I am working on a fix for this so it will work if just have the Bandcamp Release Url.
What SongKong cannot do anymore is use Bandcamps search to find artist and albums, but I am looking to see if I can use a guess pages from name and then update approach
