Using Firefox mobile for android and GBoard. I've selected Firefox as my auto fill service. A few official apps (at least one banking app, for example) that I've downloaded from the play store that report the following after I unlock and select the correct password: "Firefox could not verify the authenticity of the application. Do you want to proceed with autofilling the selected credentials." I can't seem to find any other report of this error so I'm curious what's going on.
