Who I have the same questioned this topic

Hello?  Any word on this? It's happening again today!! Another group text conversation with the same set of 6 other people. Some texts come through OK, some texts come through but significantly delayed (around 2:00 I received one that was sent about 1:15 - that's just a short text MMS, no images or other attachments), and some texts fail with a "message not delivered" error. Those in the last group leave a "download" link which just gives the same error again if I try to download the undelivered message.

Plus, I **STILL** cannot download the messages sent two days ago which went undelivered.
