Hola @LawnMower, Intermittent issues are the pits because temporary fixes make things seem fine and then they break again. One thing that I have seen with intermittent messaging issues for SMS or MMS is congestion in the "mailbox" rather than the network side. If the messaging app that you are using (messages on your phone or messages.google.com) has too many messages saved, new ones have a hard time finding a "place to sit." Restarting the phone will usually free up enough temporary memory to allow the messages that are pending to come in, but new ones are stopped at the door. MMS are larger files by nature and are usually the first to be affected. Have you had a chance to go through your messaging apps and delete as many messages as possible?

Thanks for that suggestion, @HeavenM !  I used to have an app on my old phone to periodically delete messages but I no longer have it.  I'll see if I can get one installed and delete some messages.  I have a lot of them

I don't normally recommend downloading apps that manipulate your phone like that because it could unintentionally affect other things as well. If you have a ton of messages and don't feel like you can do it manually, then do what is best for you. I just wanted to give you some caution. Let me know how it goes

I went ahead and downloaded an app that does backup to my Google drive.  It works well and I can access the backed up messages and attachments through it.  That way I can save any pictures I'd like to save.

After backing up and verifying that it worked, I went through the fairly laborious job of deleting all the texts, including spam and blocked, from my phone.  That took a few minutes but now it's done.

The next step is to see if all that had any effect on my "failure to send" and "unable to download" problem.  I'll report back here with anything I learn.

Thanks again to all for the help.
