Hey Nico,
Apologies for breaking your workflow!
The SG Review site setting has been automatically disabled as part of Shotgun 8.20 release, as explained in this FAQ: ‘Shotgun Review for RV’ deprecation FAQ
The 8.20 release is part of the “soft deprecation” to see if there’s anything that we’re missing from Screening Room before removing the SG Review app setting for good. We highly recommend migrating your workflows as the hard deprecation is approaching fast. We’re looking to deprecate SG Review app early next year.
The FAQ has been linked as part of a site banner warning of this change, for a few weeks now. Is there another way that you’d prefer to be notified that would work best for you?
Thanks,
Alexa
