NASA did not provide a date but it looks like this issue was discovered and acted upon on Dec 7 or 8.
The graphic below shows the schedule for Voyager 1 comms via DSN, generated on Dec 7. Normally, the downlink rate is 160 bps. On Dec 8, it was switched to 40 bps. And again on Dec 10. Some special commands for the FDS were also sent.
Since then, the D/L rate has been switched between 160 bps and 40 bps a few times with additional FDS commands uploaded.
