When sending warnings to players within an instance after opening up a player profile using the "More Options" menu found through the "Three Dots" menu (next to the reporting button on a user profile); the "Warn User" button doesn't provide a confirmation window to confirm if you would actually want to warn said player. This is inconsistent with the current "Warn User" button found through selecting a user after selecting a user capsule where that one does provide a confirmation box.
Solution would be to restore consistency with providing a confirmation box, as the "Kick User" option from the "More Options" menu does provide this confirmation box as expected.
