You know how they list factors that are hurting/helping your score? Well, on Equifax this is under 'hurting your score:'
"Lack of sufficient credit history on bankcard or credit card accounts"
Hmmmm... Let's see. I have 15 active cards. My oldest card is 30 years old. My AAoA is almost 8 years. I have a perfect, spotless payment history. Nothing derogatory whatsoever. My scores are in the 810s right now, a little lower than usual.
What am I missing?! If THAT lacks sufficient credit history, then what would qualify?
By the way, my 'hurting' factors also include the obligatory "Lack of sufficient relevant first mortgage account information"--but I'm definitely NOT going to run out and mortgage my house just to improve my FICO scores! 
Those "helpful" hints are so meaningless.
Last month I showed the following:
You have an insufficient number of accounts that are currently paid as agreed.
Number of your accounts currently being paid as agreed
6 accounts
The FICO® Score considers the number of accounts showing on time payments. Generally, the higher the number reported the lower the risk. Compared to other people with a similar age of credit history, the number of accounts you have that are currently paid as agreed is low.
FICO High Achievers have an average of 6 accounts currently being paid as agreed.

I refuse to get obsessed with these negative reason codes; they so often make no sense, as in the instant case.
You have high scores. It seems that the higher one's scores, they more senseless the negative reason codes become.

@SoCalGardener, one guess is that you still have a point or two available for AAoA (average age of accounts). Another guess is that this reason code might be focusing on the ages of your youngest accounts. According to posts here, an AoOA (age of oldest account) of 25 years should eliminate the code for that.
My AAoA is 106 months on two reports and 103 on the other. AoOA is 20 years on all three. I think my AoOA is the likely reason when FICO complains about my short history.
My oldest is 30! So I think this once again proves that when it comes to credit scoring, it doesn't have to make sense!
I generally don't pay much (if any) attention to the 'hurting' reasons given by various sites, only when something jumps off the page at me--like this one did. I guess I'll just treat it the same way I treat the other nonsensical 'reasons'--ignore it!

Fico codes give you an idea of what is lacking in that category, and it's all based on algorithms.
That's how they're supposed to work, anyway! 
In my case, telling me I don't have enough experience with credit [or however it was worded] is just ridiculous, and there isn't an ounce of truth to it. So whoever came up with that particular algorithm needs to tweak it a little!
At least the 'hurting' reason of not having recent mortgage experience is correct. I don't like *seeing* it, as there's no way I'm going to take out a mortgage just to improve my credit scores, but at least it's true. The 'lack of sufficient credit experience' on the other hand? Nope!
@SoCalGardener I have come to view those reason codes as completely useless. Especially when your credit is good. I scratched my head about 3 times 8 years ago and then moved on... aint got time 🤣
Here's another factor hurting my scores, according to Equifax today:
Your largest credit limit on open bankcard or credit card accounts is too low
FWIW, my largest credit limit on an open card is $15,500. THAT is too low? 
And, as always, the obligatory:
Lack of sufficient relevant real estate account information
