Do you have separate online accounts for your personal and business cards?
In my case, I have 2 separate accounts for personal and business cards. I didn't want one same account for all my personal and biz cards. I think because of that, I can't transfer biz to personal and vice versa cos I don't see the personal cards on biz and biz cards on personal accounts. Years ago, we used to be able to just manually add the card number of where you are transferring the points to. I may have to call chase to transfer the points to.
