Hi, I already purchased plan 1 (1 code), if I want to have voice cloning feature included, does it means I buy 2 more codes (i.e. Plan 2 $158) to get to Tier 3 (total 3 codes)? Also, what is included in the voice cloning feature for Tier 3 (e.g. how many voice cloning profiles? and what is included as voice cloning credits?). Please advise.
