Unable to preview/publish on Studio

Hi, I have been trying to log in to studio (Gmail sign-in) to preview my project. But the pop-up does not recognise my id and returns a message saying “This browser/app may not be secure.” Have allowed 'less secure apps on my Google account, have allowed access to Zapworks through the firewall. Anything that I am missing?

I’m having the same issue

I saw this issue multiple time with students and different computers. I never understood what is really blocking. Most of the time it’s under Windows and Internet explorer… sometimes the problem disappear.

I’ve also been having this problem and I’ve tried on different computers and reinstalling and it just doesn’t work. Not even turning off less secure app blocking on the Google account works. I have no idea what to do at this point and I have seen many people with this problem but no solutions that work.
