Where is the app for the WorldServer Packages

Question

Hello, 
 Can you help me with this issue: I have a license for SDL Trados 2021 Freelance, v. 16.0.2.3343, installed in November. Now I must upgrade it to SDL Trados Studio 2021 SR1 (build 16.1.2.4090), because I have to download the app for the WorldServer Packages for my biggest client (requires this new version). The problem is, that I did not receivethe messages for this update/upgrade. I tried to search for it manually, but it did not work. Is there any settings or something I can do to install this new released version? 
 Thank you in advance for the answer. 
 Best regards, 
 P. Petkova

 If you don't know, just look here:
