EmailPlus error

I'm getting the following two errors when trying to send alert emails using the Seq.App.EmailPlus (v3.1.0-dev-00179) app, Seq 2021.2.5647:

Hi @bbeardqrails - this is a known issue in the Seq version you're running; restarting will resolve it temporarily, but updating to the latest version will prevent it happening again in the future.

HTH!
