Every time I type on an app like Drafts or Mail I see this annoying, terrible delay. I use an iPad Air under iOS 12. I know it's not the fastest device in town, but as soon as I did a clean update to the current OS a long time ago, I saw that it could handle the system pretty well, and that included a fluid experience writing in any app. Now it's unbearable though. I tried a test — closed all the apps, restarted the device (hoping that could fix any memory issues) and tried typing in Drafts or Mail. It did no good. Ideas? (That doesn't imply a classic "restore your device".) Is this "normal"?
