Users in "view-only mode" get stuck in the Acceptable Use Policy

Background

I work with a company that is using Viva Engage. In some of their Communities, they have set restrictions so that only those who are Community Admins are allowed to post posts. When a Community Admin create a post and attaches an Excel file to the post, the Excel file is editable by all members of the Community. (Actually, it would have been optimal if the setting that limits who can post posts had also limited the ability to edit attached files, but that is not the case.)

The setting i have tested

Therefore, i tested "Manage user privileges with view-only mode in Viva Engage". As a Viva Engage administrator, I opened the Viva Admin Center and opened the "Governance and Compliance" tab. Under this tab there is an option called "User Management" where you can "adjust user settings surrounding the creation and visibility of contents". This sounded good, so I added the users that I wanted to limit these possibilities for so that they would basically only have read-only access to the community.

The problem that arises

This is where the strange problem arises. When these users, who I added under "User Management" now enter a community, the window with "Acceptable Use Policy" appears and it is completely OK but after that there is no possibility to accept, close or exit this window. Is this a bug or is there any additional setting that I have to turn on for this to work as intended?
