I tried to work with Assets for the last couple of days. And it seriously was annoying from the beginning to the end.
The Website was extremely slow. The Synchronisation took forever. I can't see about how long the upload is going to take. And One Videofile with 1,92GB couldn't upload at all. And I have no clue why. An error message would be useful. And after going through all the trouble, my client is not able to download the files.(again here no valid information as to why it is not working).
I will have to switch back to Drive. A shame. I am usually a big fan of the Adobe products.
