I recently logged out of Netflix and when I tried to log back in I received the "Update Required" message.
Searching on useragents.me I used the latest Windows Desktop user agent for Chrome browser :Chrome 121.0.0, Windows 10/11
The user agent string: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36
This user agent fixed my problem
