I have installed duo at a customer which works fine with a push notification when the customer is connected to WIFI. However, when the customer is connected to mobile internet via 4ghz, the customer only has the option to log in with a code. by default he then has 10 attempts. I want to increase this number to 25. I have already adjusted this in the portal, but the number of login attempts remains stuck at 10. My question is how do I change this?
