I am a teacher at a high school and myself and students can no longer "Add layer from file" from Google Drive. This has worked in the past. The error we get is below. I have reached out to my school boards systmes engineer about it and says it's something on ESRIs side. I know there are alternatives to adding files, but I find using google drive to add files is easy.
Hey @CameronWheelan
This definitely appears to be some type of bug or deprecation of service, you may need to reach out to Esri Support so they can investigate on the back-end of things. You mentioned this is happening everywhere, have you tried downloading the file and then uploading? For the time being a work-around may be the best approach until Esri gets back with you!

Thanks for the response. I have been downloading the file to the devices and uploading it that way.
