On 13 September 2021, 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 some new file access requests. Access to these files won’t change for people who have already viewed them.
What do I 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 posted publicly. Learn more
After the update is applied, you can avoid new access requests by distributing the updated link to your file(s). Follow instructions in the Drive documentation
