uverse app - iphone/ipad ios 14 - local network privacy permission

If the app did not ask for local network access and in not listed in the local network privacy settings of the iphone/ipad, how can I add it to the list and grant permission? Deleting the app and reinstalling did not work. This is an iPad on ios 14... that was setup using an iPhone that had the app and already had local network access. Apple support and community is of no help.
