Multipart WAP messages from verizon being detected as individual single part messages
I am using ModemManager 1.18.2 on PostmarketOS on a Verizon MVNO (Ting). When I receive MMS WAPs, they come in as transfer route MT messages, but appear to not be merged together as a multipart message:

<<<<<< RAW:
<<<<<< length = 20They appear to have the same message-id, and my understanding is that these should be treated as a single multipart message. Given that as of #257, others report success with WAPs on Verizon, I wonder what is different about these messages. Are there any next steps for debugging this?
