Using Gmail, if I click on the 3 horizontals bars top left, near Inbox, on top I see my primary account (a) with an arrow on the right. If I click on this arrow, I see 2 secondary accounts (b) & (c).
Going back to my inbox, I want to reply to an email using address (b). I click reply and the arrow next to my primary address. There I see: send email as (d) or (e) - i.e. 2 other secondary addresses that I had created very long ago.
My questions are: 1. how can I remove (d) & (e)? 2. how can I see (b) & (c) instead?
If I go to Settings/Accounts/Google, I only see (a), (b) & (c). (d) & (e) don't appear, therefore I can't remove them.
Thank you in advance for your help
(Android 6.0 but I had this problem before this version)
