How to delete mass messages in account notification?

Not the ones in countries or enterprises , those can me mass marked and deleted

the ones in main game account

sorry , duplicate thread

Click on the picture of the player next to the message to select it. Then just go down and select all the ones you want to remove then click the trash icon on top right. Only way I have found to do it.

thanks, at least its something much faster than entering every message and delete
