When I write draft mails on the computer and try to open on the iPhone Mail Client, it does not work because of the encrypted message you can not disable. The problem is already known for a long time but unfortunately I need now the whole design mails also on the road. Can someone fix the bug?
Diff:
This is no bug, it's a setting (that defaults to "save drafts encryptedly"). Please open your ACCOUNT settings in Thunderbird, section OpenPGP. There, UNtick the downmost checkbox "Encrypt drafts".
Mind that drafts saved on remote folders will be visible to your service provider then.
( You obviously do that as you continue to write messages on your phone which you started to write in TB.)
it works
