Phoenix 1.6 App upgraded to 1.7 warning about layout conflicts.

[RyanFleck]

After upgrading to 1.7 and navigating to any Pow layout, I am met with this information.

Has anybody seen this? What did I miss when upgrading my Phoenix app?

warning: conflicting layouts found. A layout has been set with format, such as:

    put_layout(conn, html: {Pow.Phoenix.Layouts, :app})

But also without format:

    put_layout(conn, {AttendanceWeb.LayoutView, :app})

In this case, the layout without format will always win.
Passing the layout without a format is currently soft-deprecated.
If you use layouts with formats, make sure that they are
used everywhere. Also remember to configure your controller
to use layouts with formats:

    use Phoenix.Controller, layouts: [html: {Pow.Phoenix.Layouts, :app}]

@RyanFleck did you ever figure out how to resolve this warning? I'm getting the same warning in my project. I'm wondering if it is because I modified the templates and haven't updated them to the new HTML approach.

Fixed in v1.0.36, thanks for the report!
