Inside Drupal views, I use some contextual filters and relationships which, I think, are provided by CiviCRM Entities.
Before Civi 5.15, some seemed to be provided by CiviCRM itself (?). Under 'relationships, for example, there was 'CiviCRM Contacts: Drupal ID' which did not say 'provided by CiviCRM Entities'.
After an update to 5.15, that relationship, and a whole bunch of others, are gone. Under relationships, the only one left is 'CiviCRM Contact: Entity translation: translations Translation information.'
Also under 'contextual filters', a lot of civicrm filters, but not all, are gone.
What am I missing ? Have they moved somewhere else ?
