Hi, I have created my own client id for uploading to Google Drive. This issue has persisted for more than a week, I have been struggling to find a solution. I thought I was being ratelimited but my usage is well under the quota limit as shown in the screenshot below, the credential was fine a week ago until I found out that I have to be verified? I don't have to be verified since many months ago, it only happened this week.
