Public share Unauthorized Exception GET/Config

Hello,

I noticed that whenever I use a different browser to visit a public share where I am not logged into Nextcloud already the app fails to render. When looking deeper with inspector mode it gives the error '.../index.php/apps/files_readmemd/config 401 (Unauthorized)' with 'Current user is not logged in'.

Now... tricky part is I don't know if this is related to the app or to the following issue from Nextcloud as around the same time these errors come up. https://github.com/nextcloud/server/issues/15689

I am testing this on Nextcloud 16.0.1 with a build of the readmemd app from last week.
