After Updating to iOS 11 I can no longer connect to the game on any WiFi networks - 2 devices and multiple networks tested - I receive “Notice Network Connection Error.”

I can still login through LTE and I can switch to WiFi after logging in without issue. Only the login process fails over WiFi.

Everything worked fine just prior to the update. uninstalling the app and re-installing had no effect.

DevicesTested: iPad Pro 2017 Model and iPhone 6S

Checking if other players reported the same, already asked the team to take a look at this issue.

I can confirm this mate, I've got an apple device, updated to iOS 11 and it will not logon with a wifi connection, no issue with the 4g connection.

Small Update, after moving to a completely different physical location (Home vs. Work), I was able to use WiFi again - maybe apple is keeping a bad auth token between updates? - I will follow up on Monday if the issue if gone when I return to the office.

I know the issue was not the office WiFi or firewalls where I experienced the problem as I am the network adminsitor for my office and was watching the network traffic on my Palo Alto firewalls and nothing was being blocked from my device before or after iOS 11 update.

Confirming, issue still occurs, only login is failing. Once the app is started there is no issue.

Agreed there, if I connect on 4g and then turn on wifi I can stay in game but what data that ends up using on my phone I can only guess, I'd hope it was using the wifi.
