I know that Butler is a default option and not a power-up option that's why deactivate power-up doesn't do anything.
but I see in "https://trello.com/XXX/account" that Butler :
" Read and write access to your account
Read and write access to all your tables
Read and write access to all your teams"
I don't want the app Butler to access.
When I click on "revoke" then 1 min after when I use trello, Butler returns 
Thank you in advance for your help.
