Stuck on mail account validation

I try to use my gmail account with emclient, but it’s stuck after gmail connection, a window pop up saying “please copying this code, switch to your application and paste it”, the code is allready paste by default but there’s no button at all to click on and enter do nothing… can’t use em right now …

Hello Guillaume,

Do you have the 2-step verification enabled in your Google account’s security settings?
