There's currently an issue where Saved Squads for certain game modes are not saving properly, most notably when accessing them from the character roster. This issue is scheduled to be fixed in the next major release, version 5.8, targeting release next week. In the meantime, there are two ways to ensure that your changes are saved.
The first way is to enter the game mode of the associated Saved Squad tab that you want to make changes to and then make the changes. For example: enter the Arena mode if you want to make changes to your Saved Squad tab for Arena.
The second method is to Copy the teams/changes from the Roster tab and then Paste them into the specific game mode tab.
We appreciate your patience in the interim.External link →
