Default email option is missing from settings
I am running iOS 13.6. I am unable to select a default email account. I have verified that I have two accounts added with email selected: an exchange email and a yahoo email. However when I go into settings > mail > under the compose section I don’t have any default email option. It ends at signature. I’ve seen other posts related to this and followed those steps but nothing has restored that setting.
iPhone 11, iOS 13
