I had the same problem today. Just in case, I would like to share one solution I found. I got this idea after reading this issue in device repo: https://github.com/plataformatec/devise/issues/3461

class Identities::SessionsController < Devise::SessionsController

  rescue_from ActionController::InvalidAuthenticityToken, with: :force_log_out

  #...

  def force_log_out
    return unless params[:action] == 'destroy'

    puts "rescued ActionController::InvalidAuthenticityToken"
    puts "force log out and redirect back to '/'"
    sign_out_all_scopes
    redirect_to '/'
  end

  # ...

I do not know if this is the best solution. If anybody has other solutions, I would like to learn them.
