What changed
From August 7, Legacy Cascade is disabled by default on enterprise tiers. On July 31 the enterprise Cascade setting had become a three-way choice (on everywhere, JetBrains plugin only, or off), letting admins move users to Devin Local while keeping Cascade in JetBrains. On August 14, Devin Local was switched on by default for enterprise customers.
Who it affects
Enterprise admins and developers who still rely on Cascade.
What to do
Check the Cascade scope setting; set it to JetBrains plugin only or re-enable it while you plan the move to Devin Local.
