I updated to 1.2.2. Don´t know what happened but I`m not able to heal in Poké Centers anymore. “Hello, and welcome to the Pokémon Center” is all the Lady says. Some spots like the Pokémon League do heal my Mons. One thing that might help: If I fly to Telnor Town (home town) and try to excit through the forest, I get a notification that it´s not safe to enter the woods without a Pokémon.
