Google is applying a security update to my file drive that I use for our downloads section particularly the Briggs Files. IF any member with downloads access can't access the files let me know but hopefully I already got all the links already updated. As with anything things don't always work fully at first and I may have miss a few. This update seems to only affecting my openly shared files with the members here.
On September 13, 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.
