"You have already added all your accounts" message with Amex

@Coach Jon and @molehill6804 - I'm having the same exact issue. In fact, it caused me to cancel my Quickbooks subscription because they couldn't seem to figure it out. **I know QB and Quicken are the same people. But QB was way too expensive for my needs anyway.

I also have multiple AMEX checking accounts as well as 2 business credit cards. I cannot get more than 2 accounts to connect. When I tried the manual add solution, it now says that I've added all of my accounts (which I have not - it just isn't finding them). I hope there is a solution soon. This is incredibly frustrating and we are getting close to tax time. I don't want to manually track my expenses again but, if this isn't fixed, I will have to bite the bullet.

@Coach Jon - I had added my 2 credit cards yesterday as manual accounts. I used the link to "add" them as regular accounts and was successful. I went into my AMEX checking and revoked the permissions from my remaining 3 checking accounts. This is the screen I got when I tried to add them as well.

I have a total of 4 checking accounts and 2 credit cards with AMEX. Simplifi has been able to add 1 checking and 2 credit cards. If I try to add anything else, I get this message.

I also noticed that, when I go into the settings on my AMEX account, there is no permission token on the other 3 checking accounts. It's almost as if the system is not even trying to access them. It just throws this error message as if it is limiting the amount of accounts that can be added under one provider. I'm not a tech person by any stretch but I understand basic mechanics.

I actually canceled by Quickbooks yesterday because of this exact issue. I thought that - by switching providers - I would be able to have full access via my accounting program. I did not realize that the same thing would happen with someone else so I'm beginning to think this is an AMEX problem. I've had 3 chats with them and, yesterday, I called them. The guy I spoke with kept insisting that it is not them. So, who is it then?

As the original poster on this thread mentioned, this all started happening around September 2025. I've been with AMEX for over 2 years with zero problems. I started noticing in my QB that I was getting the "cannot connect" error message for my accounts and it's been a battle ever since. I hope you can help. Sorry for the long-winded response.

@Coach Jon - as I mentioned in my original comment, these accounts have been opened and maintained - simultaneously - for the past couple of years. I also mentioned that I had revoked the permission for Quicken before attempting, again, to reconnect the accounts.

I'm happy to try and manually add the accounts as I did with my 2 credit card accounts. However, I am not optimistic. Nevertheless, I will try and I will reply here to let you know the outcome.

@Coach Jon - Yes. All of these accounts are within the same login. I only have one login with AMEX including the checking accounts and credit card accounts. They keep everything within the AMEX Blueprint portal.

Good morning, @Coach Jon:

I carefully followed your steps this morning. I revoked all access for Quicken in my AMEX accounts. I converted the 3 accounts I had in Simplifi to manual. I added the remaining three accounts manually. So now, my accounts are shown as this in Simplifi:

Initially, it linked Amazon Business Prime Card, Blue Business Plus Card, and Operating. I added Retainers, Savings, and Taxes. This list consists of ALL ACCOUNTS at AMEX. I have screenshots showing that permissions were revoked from all 6 accounts individually but I won't upload them unless you need them.

This is the landing page when I log into my AMEX account to access ALL ACCOUNTS:

After signing in, this is the next page:

After selecting one of my checking accounts, this is the next page:

When I go back to Simplifi to now connect ALL ACCOUNTS from manual to linked, this is the address of the pop up screen to authorize access for Simplifi:

After selecting ALL ACCOUNTS shown and clicking continue, I now get this message on the confirmation page in Simplifi:

I tried a second time and this is the initial pop up asking me to select ALL ACCOUNTS:

Since there is a lot of info in this comment, I'm going to answer your questions in a separate comment.
