Hi LeahPetro,
If apps are not working as expected, then we recommend that you try the steps here: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support
To perform the steps in the article we suggested above, click and open the link, read the subheadings below, and try each step.
1) Close and reopen the app
Force the app to close. Then open the app to see if it works as expected.
2) Restart your device
Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.
3) Check for updates
To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.
4) Delete the app, then redownload it
Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.
We recommend the steps above because they will show you what to do if an app doesn't work as expected.
If you’re still experiencing the same issue with logging into your apps, then we suggest trying the steps here: If Safari isn't loading websites or quits on your iPhone, iPad, or iPod touch - Apple Support
