For those who having problems with the update loop on Anno 1800. This was resolved on the Valhalla forums.
- Log in\open Ubisoft Connect update your games
- Go into settings\Network unclick Enable automatic game updates for recently played games
- In settings\Download unclick Enable automatic game updates for recently played games
- Close down\log out of Connect then log in\ open Ubisoft Connect this will fix the Update loop.
In the meantime this will give the Ubisoft team more time to fix Connect
Thank you.
