I'll be waiting until I've had the cards for more than 12 months before I request a CLI with them.
I don't mind taking the HP when I do, I used a loophole to get 2 cards with them on a SP, so kinda owe them a HP anyway.
My request for a increase was denied and I will be getting a letter in 7 days letting me know the reason... now I wish I had waited the full 12 months

Having just got a Truist Enjoy Cash last month, I will be following this thead to find out...
Denial reason: Total of all balances on bankcard or revolving accounts is too high. Additional data point: it now shows I am not pre qualified for any of their cards when I was just 2 weeks ago.
I did recently utilize one of my cards limit by 39% from the usual 0% to take advantage of a balance transfer offer and I guess Truist did not like the larger than normal increase in my reported debt load (Over 5K extra). I'll try again after I have taken advantage of the offer and repaid most or all of the debt. I'll see if my pre approvals are back first and if they are then I will submit another CLI request and report what the outcome is at that time.
