How many Chase co-brand cards can I add to my instacart account and receive monthly credit? I added more than 5 co-branded cards, but seems like after 5th one (starting with 6th one), it starts to give out error message. So I suppose maximum is 5? But I don't see any maximum mentioned in the T&C of instacart membership. I also have Chase Ink Unlimited, and Chase United Explorer, Quest, Club Business in my Instacart account, which are separate from the co-branded card benefits.

If maximum number is 5 for co-branded cards, then I would probably need to open a second instacart account to use the additional Chase co-branded card credits... but I just want to confirm if 5 is the maximum allowed for co-branded cards?

Another question is, how do I unlink Chase United Quest from my first instacart account if I want to use it on the 2nd account? Cuz since Club Business already provides IC+ until 12/31/2027, I would have to pay for the IC+ on the 2nd account after next year, so Quest gives the 50% discount on the renewal, so I want to move it to the 2nd account... so how would i move the Quest IC+ benefits to the 2nd instacart account?
