I noticed that "Today's" bank transaction not being upload via bank connection, they aren't picked up.Has anyone else have this issue?

I'd be glad to help you with your bank transactions, @contact21.

Since the latest transactions didn't download automatically, you can do a manual download instead. Just go to the Banking menu and select the Update tab. 

However, if the number of transactions didn't increase, you can refer to this article for additional steps: What to do if bank transactions won’t download.

For other articles you can use related to banking, you can visit this link: Banking for QuickBooks Online.

Keep me posted how it went. I want to make sure you're able to download your bank transactions today. I'll be here to help if needed.
