Limited use in 3rd party apps with share sheet removal

@aclauss:

You can’t save passwords in 1Password from within third party Apps anymore. The action extension did support this

The 1Password AutoFill credential list is able to save passwords from third party apps.

Also the iOS fill feature is not always available and does not always work where the action extension would have worked.

This is a function of iOS, not 1Password. If an app is not flagging login fields properly so that iOS Password AutoFill can offer to fill into it, that would be best brought up to the developers of that app. Here's some reference documentation to forward to the developers: Password AutoFill | Apple Developer Documentation and Supporting Associated Domains | Apple Developer Documentation

Older devices which can only run iOS 12 (iPhone 5s, iPhone 6/6 Plus, iPad Air, iPad mini 2/3, iPod Touch 6G) do still get the 1Password update, but on these devices filling out forms (or saving them) from within Apps is NO LONGER POSSIBLE AT ALL!!!! Even from within Safari you don't have access to the passwords anymore. 1Password is completely useless on these devices because NONE of the ways to access passwords is available on these devices anymore: The iOS fill feature does not have 1Password as an option, the action extension is not available, nothing works.

Password AutoFill was introduced to iOS in iOS 12. All of the devices you have mentioned should have the ability to enable 1Password as a Password AutoFill provider in Settings.
