P2422HE to P2422H, daisy chained, not waking P2422H? #2

We have laptops connecting via a single USB-C cable to a P2422HE, then daisy chained via DP to a secondary monitor, a P2422H.

We have observed that sometimes the secondary P2422H will not wake from sleep when a staff member returns to their desk? Pressing the power button is needed to wake the P2422H. The primary monitor comes back on just fine.

We're having the exact issue described on this thread, but I cannot reply to see if there was a solution?

Any assistance would be appreciated.
