Pokemon doesn't follow me!

So today after realizing 1.2 was out I lost my previous 1.1 save file, so I decided to start anew, but when I faced a trainer and lost, my pokemon didn’t follow me anymore. In 1.1 I always used P to refresh and make them follow me but the P option seems to have dissapeared in 1.2. Can anyone help me?

what pokemon is it? the same thing always happens to my D. Venusaur. I just have to enter or exit a building

It’s Piplup

try doing what i said earlier. Walk in and out of a building

Alright, thanks. I was in a cave so that’s probably why I didn’t think of that. It worked.
