Hi fierceclever
Thanks for reaching out 🙂 So sorry for the Ultra forum issue, we’re looking into the matter urgently!
Unfortunately, it isn’t possible to add Sharing to the Ultra social sharing function. What I recommend doing is disabling Ultra social icons in Theme Settings
and instead using: https://jetpack.me/support/sharing/. If you’re activating Jetpack for the first time, I recommend going to Jetpack > Settings after activation and bulk deactivating all modules. Then, activate Sharing and any other modules you’d like to use. Once activated you can configuring Sharing to display Email and the other networks you’d like to use. You can also choose the locations you’d like to show the icons.
Please, give that a go and let me know how it goes 🙂
