One of my 4 Marcus CDs was not posting monthly interest accruals, and it turns out that it was not set up for online transactions. When I tried to do the setup, Quicken's "Search for Your Financial Institution" dialog did not present Marcus as an option, neither when searching for "Marcus" nor when searching for "Goldman Sachs."
More clues:
I tried the Reset Account option on one of my other Marcus CDs, thinking that might kickstart it to do the online setup for the missing account. Instead, it removed the online transaction setup for that account!
My 2 other CDs seem to be OK … for now.
Searched the Alerts forum here and saw nothing on Marcus or Goldman Sachs.
