Hi @kurdit

What version are you on?

You should be able to go to Kibana - Stack Management - License and revert to basic

Or

Delete the license and start basic

hi, i have ELK 8.3.3. I already tried these methods

POST /_license/start_basic?acknowledge=true

{
  "basic_was_started": true,
  "acknowledged": true
}

and

DELETE /_license

{
  "acknowledged": true
}

but the license still remains

    "status": "active",
    "type": "platinum",

in Kibana -> Stack Management -> License Management

"Your Platinum license is active"

I would open a support ticket then...

ok, thank u
