I have a Power App which I have shared with external users. The users have been added as guest users to the Environment in ADD, they have the Power App shared with them and have Edit permissions to the SharePoint lists that the App is connected to. The user can open the Power App and access the relevant pages but they cannot see Radio buttons or any other content that's data is based on the column settings of its respective SharePoint List Column.
I can't understand why the external users have access to everything in the correct way but still cannot use the form as it is intended.
This is an example of what the page should look like

The Radio buttons are based off of the SharePoint List Column

What my external user sees when he opens the form, the choices for Additional Features are manually entered hence why they show up. Changing all of the options to be populated manually is not a solution for me as the scope of the project states that they have to feed from the SharePoint Lists.
