Anyone on dedicated not able to open testflight for native app?

We’re building a native app for an app on a dedicated plan, we occasionally get a bug on web when trying to enter the bubble app which says ‘user does not have permission’, but we get in if we try a few times.

On native however we just can’t access the app using bubble go, clicking the branch just says we don’t have permission. does anyone know a workaround here or is this a known bug?
