I cant move at the start of infinity for plants

what are you playing ?....perhaps latency issue? Have you been able to play yet? 

Im playing pvz gw2. and every time i try to do the plants infinity challenge i cant walk or shoot around. Im stuck in one place. i havent played in two day and still is doing the same issue.

are you on pc or x1?

I have a very simmilar problem if not the same but with the zombies infinity mode. Im playing in pc

this fixed it for me:

Plants: spam press the 1'st ability button (by default 1) it should make you go fast enought to get to the time thingy and allow you to move 😉 

Zombies: seems to be a bit diffrent go a bit to the right before using the 1'st ability hope this has helped you 😉
