Review on Belkin F4U110Bt Thunderbolt Upstream Transfer and Charging for 3840X2160 by Justin Miller

I think the latest OS patch (Macbook Pro 13' 16gb 2019) from Mac disabled Thunderbolt 3. It can still do everything, just not at the same time. I need to connect the power cord directly to the laptop and not to the docking station, otherwise the device will not connect displays to monitors. This is a strange error and I hope the software can fix it soon. 09/13/21 - still no solution - cannot recommend this product.
