(this has been discussed at least since 2022, and has not been resolved for some). Wife and I have 8 accounts with chase. Wife has 3 and I have 5. We each have a separate account/login. We have been using this setup for years. Two days ago ALL the chase accounts had the red circle with the line through it indicating they were not linked anymore.
I did the option to relink my Chase accounts. Once they were linked, quicken warned me about each of my wife accounts indicating they were not found and I may want to unlink them. It then proceeded to unlink them on its own. At this point the sync started working for my accounts. There were no errors presented.
I then started to relink my wife's account. Once I logged into Chase and relinked her accounts, it returned to Quicken and started the update at which time it gave me the warning that my 5 accounts were not found and I may want to unlink then. Again, it then proceeded to unlink them on it own. At this point the sync of my wife's accounts worked with no errors.
However after my wife's sync was over, my 5 chase accounts had the red circle with the line through it indicating they were not linked anymore.
This would go back and forth, so that Quicken would only allow one Chase account to be linked.
As I said, if you search for "Multiple Chase accounts" you can see people have been having this same issue for years. Mine worked great until 2 days ago…
