From yesterday night to today my email accounts have disappeared from official program. I did no change meanwhile (just slept).

In the settings they seem ok, I have tried to disable and re-enable them without any change (and I also restarted the device). But in the mail program, it is said that I do not have any, and link to create new one (in an account page that is empty).

Does someone had the same problem? How can I solve or at least debug it? Do you know how to get the sync logs?
