This fixes my 308 issues

Open as 'source code', plist file, search for LSApplicationQueriesSchemes, then add/modify as needed.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbauth2</string>
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbshareextension</string>
</array>
