So, It's been years I had set my non-Gmail Google account that uses 2-step verification to my iPhone, just to get some Calendars I have subscibed to, through the Apple Calendar. For years, there was no problem at all, I used my app-specific password and all went fine. Currently, they made it so that you no longer need to use an app-specific password, a window straight from Google pops up and you have to enter your credentials. After you do so, you get an sms with the code, that you have to enter in order to proceed. So, after the code gets accepted, right before the menu where you get to choose which Google items you want to sync (Mail-Contacts-Calendar etc) the procedure is interrupted and you have to do it all over again (with no success). I tried another account that has Gmail set up and it works fine so I guess the problem is that my Google account has no Gmail address under it... Anyone else with this problem that has found a solution, without setting up Gmail? Thank you in advance!
