Why does the bot show Android when I play on console or PC?
Android is the hosted bot's fixed platform setting. It does not mean that your own Fortnite player must use an Android device.
Read the correct account
The platform belongs to the bot account connected by the service. Your console or PC remains the device running your real player.
Leave that value alone
The panel rejects platform changes. Re-entering a console platform name will not make the command supported.
Diagnose the actual problem
If joining fails, compare Epic display names, friendship and the current party first. Read any permission warning on your player's Fortnite screen before repeating the invitation.
