For context I changed my email through Kabam support in September everything went smoothly but the summoners market sometimes shows my old email that was used on a previous account it doesn’t affect my ability to use the summoners market but it still displays incorrect when I’m signed in
I successfully changed the email shown in the webstore after opening a ticket with Xsolla support. It was not easy but once they understood what I meant the operation was smooth. In the ticket you will open, don’t forget to mention that you want to maintain your purchase history
