Hi guys, I have an issue that is scaring me a bit about possibly losing my account. 

I created my Strava account with facebook login years ago but want to keep away from it. Since then my FB email has changed but strava kept my old deleted email address when i created the strava account with FB login. 
Do any of you know of a process to change it ? The change email requires a password but which one since i use Facebook login and the email is not the current one of my facebook account?
I currently can still use the strava login with facebook but fear I will be blocked using normal login because i don’t have access that old and deleted email address.
