I have a user helping with uploading documents to various team spaces & she has Write permission for one page within the spaces where the documents are housed. We subscribe the team members at the document level to receive version updates automatically. 

This user cannot see the correct teams to subscribe when she tries to adjust the subscriptions when uploading the original document. Does she need a higher level of access for that page or need to be something like a space administrator (not necessarily our desired access level)? Thanks for your help.
