In the past, Displaylink has always worked with this dock, after updating to Sonoma no longer accepts a third monitor. Is there any chance that this problem will also be solved?

Hello Broadband,
The dock in the link doesn't seem to use DisplayLink technology as it only supports 4kp60 as a single display and the max resolution drops to 1080p in 3 displays. That sounds like MST as the DL-6950 max resolution doesn't vary based on number of monitors connected.
You either have an hybrid dock looking the same, or it isn't DL at all. In either case, the 3rd output would not be driven by DL technology and the DisplayLink Manager app doesn't interact with it/them.
I'd recommend contacting the seller/manufacturer as they may have a firmware update.
It would not be the first time that a change made in macOS (via an OS update) means the chip need an update.
