Unsent message notification won't go away

[fuchsia_pixie]

I have a HTC One S, it's my first smartphone (had it for a couple of months), so I'm stll learning about all the different bits, updates, etc.
A couple of days ago I installed the new Android update. There weren't any issues at first (except that my favourite clock was gone, but that's another story). :'(
About an hour after installing the update, I was having an sms conversation and an undelivered message icon appeared next to the person's name in the message list. I have gone through the message thread and there are no undelivered/failed messages. I have googled this problem for two days and tried some suggestions, ie - using the History Eraser app (didn't work), clearing memory cache (I can't even find that option anymore in Settings after the update), restarting the phone. Trying to avoid doing a factory reset because I don't want to lose all apps and data, etc.
Has anyone had the same problem? It's been slowly driving me mad for 2 days now. Please help!! :-\

just hit the red triangle and it will attemp to resend. once it does it will go away

Thanks for your reply
Unfortunately this triangle doesn't work like that, because there is no actual failed message. When I hit the red triangle it just opens the message thread.

I know. Im not talking about the Notification... You have to find the message that didnt send. it will have a red triangle next to it. hold that message and delete it

I know, but there is no message with a red triangle next to it. The red triangle only shows in Inbox view, not in thread view.

I would just delete the whole thread then. if that doesn't fix it.... I have no clue.

I get random Failed To Send notifications on my Note8 and S8 since the latest update. The messages are going through but are being shown as Failed. I am very open to suggestions as to how to fix this issue.

Thanks,
