Suddenly, I am getting this error when I try to log in to my Tiller feed for my Excel file using my Google Account. I have tried three different browsers. Initially, I thought it was due to windows 11 on a new laptop, but I am now getting the error on my windows 10 laptop as well. Any known solutions?

@lorrainedamico You can get around this error by linking a Microsoft account to your Tiller subscription and then using that account to sign in to Excel.
