Why did push notifications stop in the iOS Readwise app?

Some users have reported that after getting a new iPhone or iPad and restoring a backup, push notifications from the iOS Readwise app stopped. We're investigating the issue here, but in the meantime, there is a fix:

Rather than deleting the app from your Home Screen and then reinstalling, go to Settings → General → iPhone Storage → Readwise
Once there, tap "Delete App" (as shown below)
Once deleted, reinstall the Readwise app from the App Store
Once in the app, Now you should be re-enable notifications.

For your information, you should receive push notifications from the Readwise app approximately one hour after the time set for your daily email.
