Good day ,
Usually an inactive marshal is substituted automatically in game after a while ,i don't remember exactly how many days , what you said you decided on skype or else .... you need to forward to the Support , with screenshots , proofs and they will verify if there is a good reason to substitute the marshal with what you say is ok for that position .
Is not so easy just to ask here to change the marshal ....just saying!
For esample , if i am the founder of my own league , i can login when and how much often i want, that is not a reason for my members to change marshal ....if they donìtlike me as marshal they are free to go away where they want , nobody force them to stay - just saying 😎
Here is the link for the Support :
I wish you good luck and have a nice day !
