TOTP passwords are auto-copied to your clipboard in the desktop browser version.
However, this feature isn't implemented on iOS. When using the "share" extension to use Enpass to auto-fill username and passwords, the TOTP code is not copied to clipboard, meaning you have to open Enpass/use the share extension a second time to get the TOTP code. This is a "must have" feature, and one your competitor implements on iOS as well. Please, pretty please, add auto-copy of TOTP to clipboard on mobile!
