My boss has a subscription to the Plus plan. I am on the free/basic version.
I just sat with him while he shared his screen, and checked all the settings. We have tried:
- to add me as a collaborator (we also tried removing me before we tried the step bellow)
- to copy the folder link + made sure the permissions are set to "People with this link can edit". He copies the link, sends it to me, and I am still not able to upload nor create subfolders. (see bellow)

What is our issue? Please help. TIA
