Crashes so hard cant turn off iPhone

Since iOS 10.3, this game will crash and freeze so hard, I cant turn off my iPhone 6S. It takes a few minutes (easily 2-5) before the phone blanks to black and then it takes a few minutes before Im able to turn the phone on again. This is with continuous pushing of the power button, or intermittent pushes. Doesnt matter. Will there be another update soon? I even tried removing the app and re-downloading it in case it was the new file system that comes with 10.3. I cant have my phone rendered unusable for minutes at a time. On the plus side, I did get a special item from the 7 day streak on a poke stop. So theres that.
