Hi,
I seem to notice a bug logging on Uplay. After the recent security update to change the password on uplay account I've notice logging in with your new password doesn't work on the client.
If you have already set your Uplay client to
Remember Me and
Always start in Offline Mode then try to use your new updated password by hitting
GO Online to login again, somehow Uplay client doesn't able to use new details you typed on the input field. It will keep saying wrong email or password. I tried resetting my password 3x but doesn't seem to accept the account details and still keep saying wrong email or password. Well the trick to get around this is set the client again to always start online mode by
Unchecking / Disable Always start in Offline Mode then restart the Uplay client and login again.
This time it works okay 
.
It seems Uplay client on offline mode then going to online mode keeps on using the previous access details and does not read the new access details you type on the login fields.
If you experienced this problem this is the trick to get around it.
Ubisoft/Uplay should check on this.
Thanks
