Who I have the same questioned this topic

I just bought a Verizon Galaxy s9 and I use Verizon's messaging app.  A few days ago, I get a notification next to one of my contacts that a text message(s) went unsent.  I know this is wrong because I went through all the texts and did not see anything unsent.  Also, I tried another messaging app and there were no unsent messages with that app.  I uninstalled and reinstalled Verizon messaging app and get the same problem.  Are you aware of similar issues?  Thanks
