We are also experiencing this with several clients. The primary card holder will download but not the additional authorized users. We have to manually import. This changed about a year ago and we suddenly started seeing it happen with all QBO clients.
The work around is to manually import the missing transactions. I agree that whenever I call support, the support team does not seem to be aware of the issue and there is no solution in site.\
This is a huge issue and has added bookkeeping time for some clients. Now that Intuit is offering bookkeeping, I am surprised they are not interested in helping fix.
Intuit - please make this a priority and get with AMEX to fix.
