Android 6.0.1 blocks attachments in Messages MMS ?

[AC Question]

Since newest Marshmallow release pushed last week to my Galaxy S5 Mini, I have been unable to send or receive any attachments (pictures) in standard messaging mode, getting an MMS failure message. Is this a known bug, and is there a workaround ? Thanks.

Make sure your APN settings are correct for your carrier.
