problem with new Galaxy A14

[JaneO]

I have used smart switch to transfer all my apps etc to my new phone but it hasn't worked with my calendar which is blank on the new phone. Also my two email accounts keep logging themselves out even though I have clicked save

This might help with the calendar, @JaneO - https://mobiletrans.wondershare.com/samsung-transfer/export-samsung-calendar-to-new-samsung.html

As for the addresses being signed out, if your old phone is still on WiFi, it could be logging the second connection out, depending on your settings and mail provider. Try taking the older phone offline, see if the situation stabilises. Good luck!
