issue with FortiToken on IOS device

Hello

We have an client who uses the Forticlient and FortiToken with a Fortigate 61E. FortiToken is not accepted when establishing a VPN connection using the FortiClient app on an iPhone. FortiClient signs in with username and password and prompt for the FortiToken which is installed as an app on the same iPhone. The error message is "invalid credential. When I disable 2FA then it successfully signs in with the FortiClient app for iOS.

However using FortiClient on a Windows Laptop works fine and the FortiToken gets accepted. It seems as the FortiToken numbers do not transmit when entering them in the FortiClient iOS app. Other people are using the same system and have no issue with using FortiToken on mobile phones. We even assigned another FortiToken to the user.

Any idea why FortiClient for iOS doesn't recognize the FortiToken? We compared the FortiClient settings with a phone which has no problem and cannot see a difference.

Thanks,
