AFW-421 — Device limit reached ​

Area: Licensing · All support codes · Reference table

Why this happened ​

Every device seat on the plan is in use. Seats free up as stale devices age out; enrolled devices are never kicked.

Fix ​

Remove unused devices, wait for stale seats to age out, or upgrade the plan to raise the limit.


If the fix doesn't resolve it, file a support ticket from the console — your workspace's diagnostics snapshot is attached automatically, so this code reaches support with its context.
