I suspect the system was overloaded with wards and stakes sending info on the new sacrament meeting policy. I finally got my letter to go at about 4:30 pm MDT today.
I saw something that said that this function can't handle any special formatting. I had a very simple word document without any special formatting. But, I saved it as a plain text message and then copied and pasted it into the message area in Send A Message. I used the formatting options at the top of the message bar and set the font style, size, etc. and added a couple of line feeds. I sent the document and for the first time today it was sent to all the adult members of the stake.
Now, maybe the system as been down all day and I was just lucky to try it when I did. I'm sure I've copied and pasted simple Word documents into the message in the past and it worked. But this is what I just did to get the message that should have gone out at 8:00 am this morning, but just was sent at 4:30 pm.
I'm stake exec sec in Taylorsville, Utah.
