There are a number of reasons why a fantasy league might want to skip a pick in the draft. Oftentimes, it's to penalize an owner for taking too long or breaking a league rule.
While we don't currently have a way for users to simply skip a pick in the draft, the commissioner can accomplish essentially the same thing using one of the options below.
Option 1 - Draft a player as a placeholder.
As commish, you can:
Press on the individual tile
Select a very lowly-ranked player (someone that your league would never draft)
This way, you can move on with your draft and that team will have a player that can't really use.
Option 2 - Draft a player, then drop them.
The commissioner can :
select a player to be drafted in that spot.
Using the commish tools on the mobile app, force drop that player
This sends the player back to the available player pool.
Option 3 - Assign that pick to a different team.
This doesn't technically skip the pick, but it does allow you to give it to another team instead.
