Depending on the device you are using, here are the steps:
Android: Me > Settings > Change Email (type in new email and hit OK)
iOS : Me > Settings > Account Details > Change your email > Save (upper right corner)
If you are trying to change to an email address in which you have already used on Abide, please contact email@example.com to delete that email prior to changing. It will not work if it has already been used, so we must delete it first. Thank you!
