A security update will be applied to Drive

On September 13, 2021, Drive will apply a security update to some of your files to make file sharing more secure.
This update will change the links used for some files, and may lead to new access requests for the impacted files. Access to these files won't change for people who have already viewed them. 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
