while im trying to read the missions list everytime i scroll down it just jumps back to the top again, making it almost impossible to read the list. very annoying. happens on mobile and pc

Been happening to me for a long time now.
Surprised that I'm not the only one experiencing this

It happens to me too.

It also likes to not update after completing a mission, so the last whatever skirmish you just finished will still show up.

It usually takes some time for the missions to update after you log on so, yes, they do jump as the list gets updated.
