News Desk: On September 13, 2021, Google Drive will apply a security update to make file sharing more secure. This update will change the links used for some files and may lead to new file access requests. Access to these files will not change for people who have already viewed them.
What You need to do?
You can choose to remove this security update in Drive, but removing the update is not recommended and should only be considered for files that are publicly released.
After the update is applied, you can prevent further access requests by distributing the updated link to your files.
Google already sent email to their clients about this matter. You may check it now.
