Hi Sheywuchcjgkeksv,
To stop being notified when new tips arrive, we recommend that you try the steps here: Get tips on iPhone - Apple Support
To perform the recommended troubleshooting steps via the link above, complete the steps in the section titled "Get notified when new tips arrive."
1. Go to Settings
> Notifications.
2. Tap Tips below Notification Style, then turn on Allow Notifications.
3. Choose options for the location and style of tip notifications, when they should appear, and more.
We recommend the steps above because if you follow them in reverse, they will show you how to stop being notified when new tips arrive.
Please let us know the outcome after giving the above steps a try.
Thanks for using the Apple Support Communities.
Cheers!
