Guests have no access to shared folders in NC28

[Karl-MCS]

On a new installation of Nextcloud 28 AIO with the Guests app v3.0.1 installed, a guest user is created during the workflow of sharing a folder by typing in their email address and clicking invite guest. The guest is given "can edit" access to the folder. The guest logs in and sets their password. They then go to Shares > Shared with you, and click on the shared folder. However the shared folder does not open, instead showing an empty path of /Shared which does not exist in their home folder, and nothing can be seen or uploaded. The share's existing contents do not appear nor does the "+ New" button. Nothing appears under "All files" either, which does have the "+ New" button but silently fails any operation.

If the same folder is shared with a link instead of the guest account, the button is present and working.

This works as expected in Nextcloud 27.1.5 AIO with Guests app v2.5.1.

[nickvergessen]

This issue still exists after updates:

• Nextcloud AIO v9.0.1
• Nextcloud Hub 8 (29.0.2)
• Guests version 3.1.0

@Karl-MCS, have you modified the config parameter "share_folder"? Link to documentation: https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/config_sample_php_parameters.html#share-folder

In my case I have set this to a custom value. My current workaround is to set it to the default value again "/". Then, every new share is displayed correctly to the guest users.

Hope this helps for now.
