I've also noticed a delay in reporting, called FICO customer service was told they post alerts "when they receive them from the credit burea's". I had a TL removed from EQ, it still has yet to be reflected on FICO. Not sure if this is the result of it not triggering or a delay in them receiving information.
I feel your pain I pay $39/month for the 3B+ but have found WalletHub, CreditKarma, CreditWise, and Experian tend to have faster updates on alerts or changes outside of when you pull your report with FICO then usually that is accurate but is limited to every 3 months for 3B and every 30 days with 3B+.
I've verified with EQ that the account in question was removed and pulled a report from EQ that shows as such over 72 hours ago, still no update on score. I'll update when it is reflected or if it doesn't until I pull a new report from MyFICO. I know there are triggers and/or criteria that prompt score alerts, I would hope or assume account removals would be one of those.
