Hello,
Go to Start > Settings > System > Notifications > Notifications from apps and other senders.
Ensure this is turned off.
Once done,
- Open the Task Manager.
- Go to the Startup Apps section, right-click the Phone Link app in the list, and set it to disabled.
If you are still having issues, in the Notifications settings,
Scroll down until you find Additional settings options.
Uncheck these both options.
