My email forwarders to Gmail seem to work. However, it says I cannot edit or add any forwarders due to the custom MX records (i.e., *.mailgun.org), which were not added by me. It says I need to delete the custom MX records, but I'm afraid to do so since I have a lot of forwarders and it will break if I do. The ones who says it's working now, do you have the mailgun.org MX records? And if so, can you still edit and add?
