Just upgraded to 2.0.0.5085. I added the ‘Download Station’ with success. The ‘Synology indexer’ is still added via the Connect menu.
I now have different errors and warnings. Error: ‘No indexer available with RSS sync enabled, Sonarr will not grab new releases automatically’. Warnings: ‘No download client is available’ and ‘No indexers available with Search enabled, Sonarr will not provide any search results’
