Restricted Application added a subscriber: Aklapper. · View Herald TranscriptJun 10 2021, 11:49 AM

This might have already been solved by updates made to operations/mediawiki-config for other tasks around the welcome survey percentage updates.

Krinkle added a project: GrowthExperiments.Jun 12 2021, 12:16 AM

Krinkle moved this task from Untriaged to June 2021 on the Wikimedia-production-error board.

I think this was fixed already, by other configuration changes. I'll check
later when I'm back home.

Not happening any more.
