We are aware of an issue with Radarr when clients try to update in in the app do NOT click update to v6 it breaks the app fully and unless you have been keeping backups it will not be able to be restored note the backup it makes while go's to v6 will be bad due to there issue. we advise NOT updating it at all until we hear from them the issue is resolved and we have tested it. If you still update make sure you have download backups before you click update this is the only chance you have to restore it but the update will fail so please do not do it.
