Hello Becks,
This is correct and these are both issues on DisplayLink today.
Windows 10 Anniversary Update saw a brand new DisplayLink driver architecture. It is lighter and much more robust than the previous architecture but we are not yet at the same level of features. We are working on delivering these features so the product you have gets everything back as it did.
In the meantime, here is how you could change the brightness through a software called Screenbright. It was quicker to develop the support for this standard than the buttons, so we did this straight away to enable brightness change.
Here is an article on how to get and use the free tool:

For the rotation, the option is only through the Windows display settings today. This week is starting the assessment of the reintroduction of this. It will be in two parts because the "auto" part is designed by Asus using the sensor information collected from our driver. Once the team has done the assessment, we'll be in touch with Asus so the "auto" feature and the sensor reporting feature can be developed in parallel, to minimise the wait for you.
I understand this is not a really satisfactory answer as there is no complete neat solution for you today. Please be assured we are working on it though, and that Asus is also pushing us hard on your behalf!
Kind regards,
Alban
