The Selection screen allows you to make changes to your team for the next gameweek. These can include transfers and selection changes.
Squad
Your squad is displayed, as currently selected for the next gameweek (your current selection is retrieved from FPL by the Players sync panel item). Substitutes are shown below your starting eleven, in order. Your captain and vice-captain are marked by C/V signs, respectively.
Tap a player to select them. Tap again to view details of that player, or use one of the buttons at the top of the screen to perform an action on the player.
Each player can be marked with yellow/red/purple flags, which indicate a potential injury/suspension/absence (a purple flag is generated by Differential, and indicates that the player has not bee playing regularly for their team). Also optionally displayed are 'upcoming games' traffic lights and a statistic about each player - both of these can be selected using the dropdowns near the top of the screen.
Once a player is selected, set them as captain or vice-captain using the buttons are the top of the screen. Substitute them for someone else in your squad by press the Sub button; once this is pressed then all other players will go green or red - this shows who can be swapped for the selected player, click on any green player to swap them.
To make a transfer, select the outgoing player then press the Transfer button. A player selection screen will display, allowing you to choose which player to replace them with. By default, the price filter is set to the amount of money that you have left to spend; only players who play in the correct position are displayed, and inelligable players are filtered out (e.g. from teams that you already have the maximum number of players from). Select a player to transfer them in.
Once you have chosen any substitutions or transfers, you must press Confirm for them to take effect. When you press Confirm, Differential will attempt to contact FPL and confirm your team. If you are making any transfers, these will be displayed to you for confirmation before they are finalised, including note of any points hits required. If this fails (ie you do not have any data reception), then any unconfirmed changes will be lost when you leave the Selection screen.
