E-mail accounts got deleted after updating to 1.0.4.20 [answered]
I have updated yesterday to 1.0.4.20 and everything went smoothly. I have 3 email accounts setup on the device. I used the new "Select e-mails" option in the main e-mail screen and selected e-mails from multiple accounts and deleted them. The delete operation was probably sucessful however it left the e-mail list in a broken state, blank screen with two three emails being displayed and gaps between them, instead of a full list of emails. I didn't investigate further.
Overnight I got a notification for 3 new emails and I soon as I selected the notification and went to the email application main screen, it is empty and displays: No accounts, Email account is not set yet etc.
So somehow all the email accounts were removed from the device. I am not sure if this is at all related with the addition of multi-select + delete in the main screen of the email application, however I am mentioning it since it was the only actions I did related to email after the update.
