If your connected SoundCloud account’s Next subscription level changes, the available discounts on your Feature.fm account will update as well to match. You can always review the available Feature.fm discounts for the corresponding SoundCloud tiers here. 

If you have upgraded your connected SoundCloud plan to the Next Pro level and have not seen the changes reflected on your Feature.fm account, disconnect then reconnect SoundCloud on the General Settings on Feature.fm and you should see the available offers will match for Next Pro users.
