What

New messages cover the cases where an enable or disable in one session conflicts with what another session has already done.

Details
  • Distinct text for a server another session disabled, and for one another session re-enabled so your disable did not persist.
  • Separate text for a server blocked by managed policy.
  • None of these strings exist in the previous build.
Evidence

was disabled in another session

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
