The only way you don’t receive forwarded emails could be if you have a filter that matches the messages. Or if it includes an action of Skip the Inbox. In such a situation, please check all the filters you have to make sure that they do not match the forwarded messages. Also, check the filter that adds the label, ensuring that it doesn’t Skip the inbox to solve Gmail not receiving forwarded emails. Remember that the checkboxes do not mark the filters and all defined filters are always active.
