A few days ago I changed from BlueMail to Thunderbird for Android phones. Everything went smoothly with the QRcode, but when using Thunderbird for Android I found out that the app on my phone was not in sync with Thunderbird in either my desktop or laptop. If i delete a message from my phone app, I`ll still find it in my desktop/laptop. Another thing: there`s no addressbook in the phone app at all, no settings. Where were they forgotten?
