Hello,
In March 2021, the support team discontinued the manual relegation service which used to allow managers to request a manual relegation (or promotion).
If you would like to be relegated to either the Pro or Rookie tier, this can be done by joining a league which is close to the end of their season and purposefully finishing last in order to be relegated. However, there's a few pieces of information that may be important if you plan on doing this:
• Make sure you join a league where promotion and relegation are activated (also that there is enough members in the tier for relegation to work
• I recommend mailing the league host in advance of you getting relegated so that they know why you're purposefully finishing last - some hosts do not like members joining solely to be relegated.
More information on the support team's decision can be found here:
Manual promotion and relegation.
Sorry that I cannot be of any more assistance with getting you relegated.
