There has been a bit of exploration over PM for this one, but just to report back here publicly too for anyone reading along at home… Interestingly, this seems to only affect created by system queries that have yet to be run at least once. A workaround for the short-term while we look into it further is to make sure the query is run before attempting to make it available to a group.
I’ll update here with more information when it’s available.
