We are sorry to hear about your difficulties with 2FA.
There are a few possible reasons that may trigger this issue:
Your device might be out of sync with the Internet time servers - when you check the settings in the application, there should be an option "sync now", or "time correction for codes". You might as well set your clock settings on the device to "auto-update over the network".
Your browsing history - please clear your Web Browser cookies and internet cache, restart the browser and try to login with a fresh session.
Browser plugins and VPN - kindly refrain from using VPN or any adblocking plugins cause they might be a reason for the 2FA issue as well.
