MX record disappearing

I migrated to CF a few weeks ago everything was fine then a few days ago one domains MX record disappeared… w.f? It was only for one domain and no other records in the zone were altered.

There is nothing in the audit logs. I have not changed anything and no one else has the account login

I do use the api and would prefer not to change the key for obvious reasons. But will if it happens again.

Updated the MX and it’s been ok for a day or so.

I’ve notice other users have had simliar issues. Is there any explanation for this ?

Thanks,
