iOS Keyboard Suggestions

Hi, I am using iOS 15.2 on iPhone 12. Been using SwiftKey keyboard for a while, but noticing issues with it lately. iOS is enabling the default keyboard forcefully, so I have to switch back to SwiftKey every time I have to type. (happens multiple times a day). This is why I am thinking to switch to the default keyboard.

However, the iOS default keyboard is not showing word suggestions, even in apps like App Store. It just shows the keyboard, which doesn’t help much, since I use suggestive/predictive words in SwiftKey all the time. What is wrong here?

PS: As part of troubleshooting, I did toggle all the settings and restart the phone as well. I have never seen the iOS keyboard show suggestion in all apps, which swiftkey does
