Go to the apple store

After the IOS update, a great deal of my apps needed to be updated in the App Store setting. You might need to plug your phone into your computer, and do what it takes to even get THIS advice to work:
Click on your face of logos in the AppStore screen. Upgrade the apps. Then open them FROM THE APP STORE - this will reset them to work with the new IOS. Not AL of mine needed this - but the ones that are more complicated, did. All good now!

If you problem is more severe - then yes, you need to see a pro.
