Devices don't sync when email is deleted
When I delete emails (using mail app) from my iPad, they remain on my iPhone. When i delete emails from my phone they do delete from my IPad. I want them to delete from all devices when I delete them.
If i use google mail app they do delete from both devices whichever device I use. That makes me think it has to be setttings in mail app but they are both set the same.
iPad Air 2, iPadOS 15
