Same here!

We have 5 accounts that haven't updated since 11/18/2021. This is the first time I've seen this occur.

Unfortunately, support is closed for the day, and according to status.quickbooks.intuit.com, all systems are functional. Hopefully a member of their IT support see these posts, as you're not the first to post about this.

** NOTE: Opening QBO in an incognito window did not help. Also tried updating the accounts in the QBO Android App (latest version), and still no update.
