We have recently updated our verification processes for our sync/connections system on our end. With this change, we have taken certain sync options in Discord offline, and sadly have removed League of Legends and Skype from the connections system.
We're terribly sorry for any confusion with the removal of these sync options and for any inconvenience this may have caused.
If you have any suggestions on potential sync options in the future, please share your ideas here: https://dis.gd/feedback ! And if you have any questions about our current sync options, please let our support team know at http://dis.gd/support!
