@Aran Billen, Thanks for posting in Q&A. Based as I know, when superseding an application, it is important to ensure that each app has explicit targeting to take effect. Superseding apps that aren't targeted will be ignored by the agent. Additionally, only apps that are targeted will show install statuses in Microsoft Intune admin center. Therefore, please ensure the device is under the assignment of the old and new apps both.
Meanwhile, please ensure the detection rule can detect different version of the app.
Hope the above information can help.
