when I click on my email app on my phone, my emails open but then close down after 2-3 seconds, returning me to my phone’s hone page!
any help would be much appreciated
It would be helpful if you said which email app are you using and on which type of phone.
Have you tried uninstalling the app and then re-installing it?
BT email app
will try to reinstall
The BT email app is hopeless, uninstall it and install a better mail app.
