Get Pin failure plugin 2.18

Wondering if there is a fix for Pin Request Failure. I am using Sierra and plugin version 2.18
When "get pin" is selected, messages shows "Pin Failure Request"

There is a new plugin that is in beta; it requires High Sierra or later.

I don't believe he considers it beta any more, though I might be wrong. The Plugin Store entry for the plugin does call out the requirement for High Sierra, though we're looking at how to add other plugin dependencies (beyond just Indigo version) to the store such that it's called out a bit more clearly.

Not a plugin problem. There's a warning in the Indigo log on plugin startup if it's an unsupported version of MacOS. I suppose I could just immediately shut down the plugin, but that seems pretty rude.
