Update MR helps getting rid of error messages. However, this does not make config_split_ignore working with config_ignore:3.2. ATM, I think the reason is that \Drupal\config_split_ignore\Plugin\ConfigFilter\ConfigSplitIgnoreFilter::create() is not even called with config_ignore:3.2 – and this might be exactly the same reason that was mentioned in #3413717-6: Error: Class "Drupal\config_ignore\Plugin\ConfigFilter\IgnoreFilter" not found → .
