I saw your new beta could handle attachment also. But on my device it isn't working. I got a German message like "Error - Please send this error so that we can help you."
I sent you the message some minutes ago. The message is:
INTERNAL ERROR: Cannot decrypt attachment some-name.jpg([EncryptionException (cannot validate HMAC) ])
For info: I changes the name of the jpg title here.
