I’ve had several recordings that come back immediately as “failed to load. A network error occurred” on this iOS version but I don’t know if it was something that was occurring on earlier versions. It also has a blue failed to load on the icon in the all recordings on those same icons but I discovered two things, first that these recordings can’t be deleted from the iOS Tablo app or viewed and second the recordings did properly complete but are accessible, viewable and can be deleted from fireTV Tablo app.
That means for some reason this iOS version is mishandling the cataloging and visibility of some recordings.
