App permissions

Morning,

I have an issue with the audience feature within the apps that I can't seem to work through. We have an app with two audiences where some of the reports are for both audiences, whilst others are for either one or the other. One audience is Entire Organisation where the other is selected members. On some of the reports that are dual audience, when members who aren't named in the selected users try to access it, they get the below error:

I have gone into the workspace, and checked the permissions on the dataset and Entire Organisation is there, with App(Reshare, Build) permissions. If I then add individual user permissions to the dataset, that user can then view the report in the app. Other reports in the same workspace that are also dual audience aren't suffering from this problem. I have tried deleting the dataset and re-publishing, and updating the app, but neither have worked so far. Anyone have any ideas?

Many thanks!
