Hi @Abhishek Dewan
Thank you for following up and I'm sorry for taking time.
Of course, my username and email address were registered in each correct Field type.
I faced the problem on iOS and I understand Enpass iOS app can not save credentials entered on a webpage.
So, I tried via Enpass Win app.
On Win 11, I deleted the item and synced with iOS. I confirmed the item was removed also from the vault on iOS.
Then, again on Win 11, I entered the username and password on the webpage in Chrome, saved them via Enpass Chrome Extension, added my email address to the newly registered item (of course in 'Email' field), and synced the vault with iOS again.
I tried autofill on iOS but unfortunately, reproduced the same result.
In this try, I found the problem did not occur with Enpass Win app: it correctly entered my username to the username field on the webpage even when the item also had my email address.
In the above try,
1. I used Safari on iOS 16.6.1.
2. The website was Twitch (https://www.twitch.tv). But I had the same problem on other web sites where they required my username but not email address, and both of them were included in one item in my Enpass vault.
I hope the above will help you fix the problem.
Thank you.
