• Hi,

    I’m seeing the following two errors when I try to validate the AMP pages using Chrome even though the page source code has them:

    DISALLOWED_ATTR type (see https://github.com/ampproject/amphtml/blob/master/spec/amp-html-format.md#canon)
    
    MANDATORY_TAG_MISSING mandatory style (js enabled) opacity 0 (see https://github.com/ampproject/amphtml/blob/master/spec/amp-html-format.md#opacity)

    Any ideas why the validator is flagging the above errors? Checking the page source, I can see the proper Canonical tag and the mandatory style:

    Thx,
