I paid for the trial of HBOMAX through one email and then realized it was included on my ATT plan and need to use that email. I can’t find how to log out and re log in under the new email. I have uninstalled several times.
When you uninstalled did you reboot/restart your Roku before you reinstalled? If paid through Roku, have you canceled your subscription at https://my.roku.com/account/subscriptions ?
