DA - you were right. Took a bit of time to figure out where the Kodi version was shown (mainly because it didn't say Kodi) and it moved from 20a1 Nexus to 20a2 or 19.9.701 to 19.9.705 between when Metropolis worked and when it didn't.
I've posted in the Metropolis thread but I doubt there will be a speedy response.
