Email Sync
Why doesn’t my email on my IPhone 11 sync with my IPad? When I delete emails off my IPad they don’t get deleted on IPhone.

Look into the mail settings, not on your ipad and phone but with your mail provider
For example on my hotmail, I had to use safari to log into my mail via the web and then find the settings that allowed the changes made on one mobile device to be reflected on another.
