Auto-Fill on iPhone 7

Each time I use the auto-fill on my iPhone 7, whether using Chrome or Safari, it asks for my master password. So I log in using my master password, then go back to the webpage and try to auto-fill, and it reverts back to requesting my master password.
It never fills.
What’s up?
