v2 should have a feature where users can create secondary accounts and have the secondary account be a child account of the user’s main account which would be the parent account.
This probably sounds complicated, so let me give you an example. (This example is YouTube and not v2) Liza Koshy’s main channel would be the parent account of Liza Koshy’s vlog channel. (the child account)
This way the two account are connected, giving users a way to easily promote both accounts together.
Just to clarify, child account does not mean an underage account.
