Guild Wars 2

I am a newish player to GW2. I played GW and Beta GW2. I played for a bit of time when the game released, but then I had a hiatus. The mission progression path has changed since release. I have no clue when or what is required to receive the next mission. I know there must be a trigger to hit to start them again, but for newbies and oldies like me many may not have a clue.

Would it be possible to add a banner in the spot where it normally tells you the mission. Something that states your mission path will resume once you hit level 30 etc..

I seriously thought I abandoned it and was a little nervous That I would have to restart a character to get the path again.

You unlock them every 10 levels. I THINK it’s said somewhere in-game, but I don’t know for sure. A notice about it would be helpful.

You are probably talking about the Personal Story.
Now it is available every 10 levels, starting at level 10, when it is available for you a green marker appears and you can follow it.
